Title: System and method for configuring access to electronic mailboxes

Description:
RELATED APPLICATION 
     This application is based upon prior filed copending provisional application Ser. No. 60/494,233 filed Aug. 11, 2003. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to the field of configuring access to electronic mail systems, and more particularly, to accessing automatically an electronic mailbox. 
     BACKGROUND OF THE INVENTION 
     Electronic mail (email) has become a very important means of communication. Users of email may have one or more mailboxes that they may need to access from a variety of devices or systems and a variety of locations. Various services may also access the mailboxes. For example, some services provide a unified mailbox that allows the user to access one or more mailboxes through the unified mailbox. 
     Services such as Yahoo™ now provide mailbox services that automatically poll a predefined list of mailboxes to determine if new email has been received. New emails that have been received in any of the polled mailboxes are retrieved into the requesting mailbox. As a result, the user only has to check the requesting mailbox to determine if new email has arrived in any of the other mailboxes. This reduces the number of mailboxes that are required to be checked periodically. Other services allow a user to access their mailboxes through a plurality of devices such as, but not limited to, mobile phones, mobile computing devices, for example, personal digital assistants (POA&#39;s) and other communications devices. 
     In order to access a mailbox, a valid set of configuration parameters must be specified. An essential parameter is the mailbox protocol through which access to the mailbox is achieved, since there are many different mailbox protocols in existence, such as Post Office Protocol (POP) and Internet Message Access Protocol (IMAP). Other parameters might include a mailbox server name or a mailbox login name. Each unique combination of these parameters defines a different configuration that can be used to access the mailbox. In some cases, there are multiple unique configurations that can be used to specify access to a single mailbox, whereas in other cases, only one specific configuration can be used. Typically, the user would have to determine these configuration parameters for each of the mailboxes and configure manually a web service associated with a web server to access each of the mailboxes. 
     One proposal in U.S. patent application publication no. 2002/0174194 provides a single web-based interface that gives the user access to a plurality of different message accounts on different message servers. This proposal allows email clients to access only a subset, namely messaging, of an IMAP server, and requires a user to establish all configuration parameters for the IMAP server functionality. Other similar proposals that require a user to determine and manually configure a web service for configuration parameters are disclosed in U.S. Pat. No. 5,968,117 and U.S. published patent application no. 2002/0112007, where message sources are established during setup and a technical support can be called. U.S. Pat. No. 6,446,114 discloses the use of an agent that searches a user database to determine a list of messaging systems the user subscribes. The agent recalls from an application database any procedures for accessing the messaging systems and logs onto each messaging system to retrieve new messages. 
     These various services that access the user&#39;s mailboxes require configuration parameters, such as a mail host and a protocol, to access the mailbox. The vast majority of users only know their email address and password, and do not know the values of the remaining configuration parameters. If all the configuration parameters had to be specified by the user, and the user was unable to provide the configuration parameters, the web service would not be able to access the user&#39;s mailboxes and the user would be denied the service. As a result, it is important that the configuration parameters for the user&#39;s mailboxes be determined based on the limited information that the user is able to provide to the email provider or other service. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of the present invention to provide a system for configuring access to an electronic mailbox based on limited configuration parameters received from a user. 
     The system of the present invention configures access to an electronic mailbox based on limited configuration parameters received from a user for accessing the electronic mailbox. In one aspect of the present invention, a database stores configuration conventions related to valid configuration parameters used for accessing an electronic mailbox of a user in a mail domain. A mailbox interface module receives the configuration information from the user that is limited in the configuration parameters required for accessing the electronic mailbox. The mailbox interface module is operative for retrieving configuration conventions from the database and generating sets of potentially valid configuration parameters based on the retrieved configuration conventions and user supplied configuration information. 
     The interface module can be operative on a web interface and a mobile device can be used by the user for inputting the configuration information, which in one aspect of the invention, could be an email address and password only for accessing the electronic mailbox of the user. 
     In yet another aspect of the present invention, the interface module is operative for generating a subset of possible configuration parameters by using heuristics of likelihood that a set of configuration parameters are valid for accessing the electronic mailbox. The heuristics comprise tracking statistics stored within the database about the number of attempts and percentage of successes using a given configuration convention. The interface module is operative for generating a subset of possible configuration parameters by also using additional user supplied configuration information. This information could be a standard protocol used for accessing the electronic mailbox, such as an Internet message access protocol (IMAP) or the post office protocol (POP). 
     In yet another aspect of the present invention, the interface module attempts to access the electronic mailbox using potentially valid configuration parameters and generates new sets of potentially valid configuration parameters if the attempts for accessing the electronic mailbox of the user from the original sets of configuration parameters were unsuccessful. The interface module then attempts access with new configuration parameters. 
     A method and computer-readable medium is also disclosed and set forth with the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout, and prime notation is used to indicate similar elements in alternative embodiments. 
     The present invention advantageously overcomes the disadvantages of the prior art that was limited to enabling access to various email accounts by configuring a desktop PC or mobile unit, such as a pocket PC, and establishing all the various settings, including the various configuration conventions and parameters, such as the ports, settings, including proxy settings, connections, email and other essential information for a POP or similar server using SMTP or other protocol. 
     The present invention advantageously allows a user to enter only a minimal set of data, such as an email address and password, and the system and method of the present invention determines through a pattern of learning and use of knowledge base what it is that one uses to access accounts and the server connections. The present invention can draw upon a database as a knowledge base and use symbolic expressions with levels of certainty to “guess” or determine mailbox configurations. 
     The present invention also allows users that have limited knowledge regarding their email account as to define their account for purposes of establishing server connections and being able to draw into one location, such as a mobile phone or personal computer, having only one email client or other means, a number of different email addresses and manage multiple mailboxes. This is advantageous because it is well known that many people have many different mailboxes that could be implemented in a variety of mailbox protocols, such as a post office protocol (POP) and different email clients and different companies. 
     The present invention has several different aspects. By using a database as a rule store and an electronic mailbox interface module as a module for learning, it is possible to automatically learn mailbox configuration conventions used by mail domains. In another aspect of the present invention, sets of potentially valid mailbox configurations can be determined by the interface module and symbolic expressions used to represent configuration parameters. 
     It is well known that in order for a user to access the mailbox provided to them by their email provider, they must provide the correct set of configuration parameters. These parameters vary, but include such parameters as a mail host, port, login name, password, and other parameters for use of their mailbox. Email providers are free to use any convention they choose for these parameters. For example, many email providers employ the use of a “defacto standard” convention for these parameters, such as using a mail host name of “mail.&lt;MailDomain&gt;”, where &lt;MailDomain&gt; represents the provider&#39;s e-mail domain (i.e., “foo.com”). Another example could be an address, such as JohnSmith@earthlink.net. The user may only know their email address and a password, for example, “password.” Information not known to the normal user could be a port number; the POP3 server: pop.earthlink.net; the SMTP server: smtpauth.earthlink.net; the domain of earthlink.net; a different user name as indicated above, the FTP server: ftp-www.earthlink.net; an access ID; and DNS address: for example, 207.69.188.XXX. 
     There are, however, are also many mail providers that do not adhere to such conventions, and these mail providers use far less obvious conventions for these configuration parameters. This makes the task of determining the configuration for a user&#39;s mailbox in such a mail domain much more difficult, if not impossible. For example, if the users email address is “john.smith@foo.com”, the email provider may use a less obvious convention, for example, if the login name is “jsmi”. As a result, it is important to capture the less obvious conventions that are specific to an email provider or mail domain. 
       FIG. 1  shows a high level block diagram of a user system  10  that is operative with an intelligent server  11  in one aspect of the present invention, which operates as an agent and mailbox interface module and communicates with source mailboxes  12 . The user system  10  includes various email clients  10   a,    10   b  and  10   c,  which in this example, correspond to an Outlook mail client, an Outlook Express mail client, and a proprietary mail client for Client X, each associated with respective source mailboxes  12 . The user system  10  also includes mailbox configuration data  10   d  for each of the email clients  10   a,    10   b  and  10   c.  It should be understood that the various email clients could be located on different user systems, as illustrated by the second user system  10   e.  The user system  10  is operative with the intelligent server  11  acting as an agent. The user system would be a wireless, mobile device, such as a held-held Blackberry unit. The source mailboxes could be located on the Internet  12   a,  a corporate intranet  12   b,  or both. The intelligent server  11  as an agent performs various functions and can include various functional modules, and a database as a conventions data store and validator modules as will be explained below. It should also be understood that some of the functions of the intelligent server as an agent could also be downloaded to the user system and operative by the user as when inputting information into a mobile device or home computer. 
     It should be understood that the software and programming used for the present invention can vary, and different applications can be used. The intelligent server  11  can use web services technology (shown by the area indicated as web services  11   a ) and include different application services used by those skilled in the art. Web services could include a combination of programming and data, which are available from a web server for web users, or the use of other web-connected programs as provided by an application service provider. Web services could use an extensible mark-up language (XML) as a standard for formatting data to be communicated. 
     Any type of arrangement can be used to access the intelligent server  11 , including a peer-to-peer arrangement, a central server, or other architecture and communications. Also, middleware could be used. Data formats could be standardized and data exchanged using the extensive mark-up language (XML), which is the foundation for the web services description language (WSDL). Different web servers could be used, including the open source Apache or Microsoft&#39;s internet information server (IIS). Other web services could include Novel&#39;s web server for users of its netware operating system or the IBM family of Lotus domino service, for example, for IMB&#39;s OS/390 and AS/400 customers. Naturally, any web server should be able to download requests for file transfer protocol (FTP) files in a preferred embodiment. 
     The intelligent server  11  can have various import agents that are designed to retrieve configuration data from email clients  10   a,    10   b  and  10   c,  including Eudora and Netscape besides the Outlook and Outlook Express email clients as illustrated. The intelligent server could include a Messaging Application Programming Interface (MAPI) to retrieve any configuration data for a MAPI-compliant email client. MAPI provides the application programming interface (API) to ensure system independence for messaging applications. A layer of functionality could be provided between applications at any underlying messaging systems and act as messaging middleware. MAPI-compliant applications could communicate through a MAPI subsystem to MAPI service providers that perform requested actions for clients and pass data back through a MAPI system to a MAPI client. Any mailbox configuration data  10   d  could reside in a configuration registry of the user system  10 . Another example embodiments, data could reside in email client specific configuration storage. 
     In the user system, the Microsoft Outlook Express mail client  10   b  can access source mailboxes  12  that use the Post Office Protocol (POP) or Internet Mail Access Protocol (IMAP). POP, of course, is the internet mail server protocol that provides incoming message storage. The more recent protocol is POPS. POP is operative with a Simple Mail Transfer Protocol (SMTP). Any mail server could run both protocols if it is to receive, store and forward messages. The SMTP protocol exchanges messages from one mail server to another and hands messages to the required POP server for an email mailbox. A POP server can receive a message and hold it until another POP server is available. The IMAP version 4 also uses the SMTP transport mechanism, but it is a more flexible protocol because IMAP allows users to store mail on a mail server without downloading all new messages to a local machine. Internet mail service, of course, run SMTP and either POP or IMAP and receives incoming messages from any source without identity checking. Thus, mail can be selectively downloaded and read, message headers reviewed, hierarchical message stores built, address book supported, and documents linked, authenticated and searched. 
     The intelligent server  11  could generate configuration data objects and format data objects using an extensible mark-up language (XML) for submission to various XML-compliant web services. The server and web service could be a simple object access protocol (SOAP) compliant service. 
     XML, of course, as an extensive mark-up language, is a subset of the standard generalized mark-up language (SGML) would allow data to be stored and published on websites and be richer in presentation. Custom tags could be created to define the content of documents. Common information formats could be created and the format and data shared on the internet, corporate internets and/or other networks. The mark-up symbols in XML could be unlimited and self-defining. The channel definition format (CDF) could describe any channel and a specific CDF file can contain data that specifies an initial web page and how it can be updated. 
     SOAP allows one program running in one kind of operating system to communicate with the program in the same or another type of operating system by using HTTP and XML for information exchange. SOAP could specify how to encode an HTTP header in an XML file, thus, allowing one computer to call a program in another computer and pass data, while also dictating how it can return a response. SOAP is advantageous to allow data to pass through firewall servers that screen-out requests other than those for known applications to a designated port. SOAP is an XML-based protocol that has at least three parts, including: (a) an envelope to define a framework for describing what is in a message; (b) a set of encoding rules for expressing application-defined data types; and (c) a convention for representing remote procedure calls and responses. 
     The intelligent server  11  could include software that is implemented as an ActiveX control as a component object model (COM) and provide a framework for building software components that communicate with each other. ActiveX controls could be automatically downloaded and executed by a web browser. Distributed object applications could be built in active web pages and ActiveX controls could be downloaded to different browsers and clients. ActiveX controls could be held in a web browser as a container and distributed over an internet  12   a  or corporate intranet  12   b.  ActiveX controls could also manage and update web content and client systems and work closely with a user interface of a targeted operating system. Java applets or similar component objects could also be used instead of ActiveX controls. It should be understood for purposes of the present invention that an object model control could also be any type of dynamic link library (DLL) module that runs in a container as an application program using a component object model program interface. 
     In one aspect of the present invention, the less obvious conventions used by a mail domain are automatically learned and stored in a conventions store. Thus, the configuration parameters for subsequent users with mailboxes that belong to this mail domain can be determined based on the automatically learned conventions in the conventions store. 
       FIG. 2  illustrates a system for automatically learning conventions used by mail domains according to one aspect of the present invention. The system is part of the intelligent server  11 , which includes a validator module  13  that determines a valid set of configuration parameters  14 . The server includes a learner module  15 , which accepts the valid set of configuration parameters  14  and generates configuration conventions  16 . A configuration conventions store  18  is operative as a database preferably part of the server, but could be separate. It stores the conventions for each mail domain. The learner module  15  is operative with a rules store  17  as a database of different rules. 
     The validator module  13  determines a valid set of configuration parameters  14  for a respective mailbox based on a limited number of configuration parameters provided by the user. In an example embodiment, the validator module  13  may try to access the respective mailbox using a set of best guesses (estimates) for the configuration parameters as provided by the service that invokes the validator module  13 . In the example embodiment, if the access attempt fails, the validator module  13  may request additional information from the user until the validator module  13  has a valid set of configuration parameters. The validator module  13  accesses the mailbox being configured by using the access protocol relevant to the mailbox. 
     In an example embodiment, the validator module  13  would use POP to access a POP enabled mailbox to verify that the configuration parameters  14  are valid. In other example embodiments, the validator module  13  may use IMAP to access IMAP enabled mailboxes. As is obvious to those skilled in the art, there are many access protocols that may be used to access mailboxes. After attempting to validate the configuration parameters  14 , the validator module  13  returns status information and the valid set of configuration parameters  14 . 
     The learner module  15  accepts the configuration parameters  14  and generates the configuration convention  16  for the configuration parameters  14 . The configuration convention  16  is a manner of formatting the conventions used for configuration parameters for storage in the configuration convention store  18 . In an example embodiment, if the users email address is “john.smith@foo.com”, and the login name parameter required by the relevant mail host is “jsmi”, an expression within the configuration convention  16  for the login name parameter may be &lt;FirstName(1)&gt;&lt;LastName(3)&gt;. As is obvious to one skilled in the art, a variety of formats could be used in implementing a configuration convention  16 . The learner module  15  may apply certain tests to the configuration parameters  14  to ensure that the configuration parameters  14  are credible. In an example embodiment, the learner module  15  will only learn conventions in cases where the mail host is in the same mail domain as the email address of the user, to avoid attempts by “hackers” to pollute the learned configuration conventions  16 . Other tests are envisioned to ensure the integrity of the learned configuration conventions  16 . The learner module  15  may also apply rules that are stored in the rules store  17 . These rules may be based on business criteria or other relevant criteria. In an example embodiment, the rules may indicate that certain conventions are not to be learned for security reasons. 
     Configuration conventions  16  that are deemed acceptable by the learner module  15  are then stored in the configuration conventions store  18 . In an example embodiment, the configuration conventions store  18  may include standard configuration conventions applicable to all domains, as well as one or more of the automatically learned configuration conventions  16  for each mail domain. Mail domains may have more than one associated configuration convention, as there may be multiple ways and protocols in which the mailbox on the mail domain may be accessed. 
     Services may then access the configuration conventions  16  from the configuration convention store  18  to generate a list of potential sets of configuration parameters when configuring access to one or more of the user mailboxes. 
       FIG. 3  is a flowchart illustrating one example of a method of learning the configuration conventions. In step  22 , the validator module  13  attempts to determine the set of configuration parameters  14  that allow the validator module  13  to access the mailbox. The validator module  13  then returns the status of the validation attempt and the valid set of configuration parameters  14 . In step  24 , the learner module  15  generates configuration conventions  16  based on the configuration parameters  14 . The learner module  15  may apply a set of tests to the configuration parameters  14  and may also apply a set of rules stored in the rules store  17 , to the configuration parameters  14 . In step  26 , the configuration conventions  16  are stored in the configuration convention store  18 . 
     It should be understood that the system and method for learning configuration parameters as described may be applied to configuration parameters for services other than mailbox access. 
     As noted before, based on empirical evidence, the vast majority of email providers adhere to a number of conventions when it comes to the configuration parameters used to access mailboxes. Almost all of the POP mail hosts in existence today are prefixed with “mail.”, “pop.”, or “pop3.”. It is likely that a user with an email address of “john.smith@foo.com” would be able to access their POP-enabled mailbox through the host named “mail.foo.com”, “pop.foo.com” or “pop3.foo.com”. In one aspect of the present invention, these conventions are captured in a data store and it is possible for the service that requires access to the user&#39;s mailbox to use the conventions to generate potentially valid sets of configuration parameters. The server can then attempt to determine a valid set of configuration parameters that can be used to access the user&#39;s mailbox. The present invention can also determine the set of configuration parameters for the user&#39;s mailbox when the user only provides an email address and password. The system and method of the present invention can also successfully determine the configuration parameters in most cases. As new conventions are introduced or are discovered, they may be easily added to the data store. 
     In one aspect of the present invention shown in  FIG. 4 , a guesser or determination module  32  is part of the server  11  and operative as the mailbox interface module and generates possible sets of configuration parameters  34  based on user supplied configuration information  30 , coupled with configuration conventions  16  stored in the configuration conventions data store  18 . Services may then use the sets of configuration parameters  34  to determine the correct set of configuration parameters required to access the user&#39;s mailbox. 
       FIG. 5  shows further details of the configuration conventions  16 . It should be understood that configuration conventions are sets of e-mail expressions formed by symbols, which can also be literals, such as a port number. In an example embodiment, a configuration convention  16  may comprise an expression for the server name parameter and an expression for the login name parameter. If, in the example embodiment, the email provider uses the login name “jsmith” and the mail domain “mail.foo.com” given an email address “john.smith@foo.com”, the login name expression in the configuration convention  16  may be &lt;FirstName(1)&gt;&lt;LastName&gt;, while the server name expression may be “mail.&lt;MailDomain&gt;”. In this example, the number in brackets within the expression &lt;FirstName(1)&gt;, represents the number of characters to be used from the parameter &lt;FirstName&gt;, ie. “j”. As is obvious to one skilled in the art, a variety of different symbolic representations may be used to represent the conventions for configuration parameters. The configuration conventions data store  18  stores the configuration conventions  16 . As new conventions are introduced or discovered, they may be easily added to the configuration conventions store  18 . 
     The module  32  generates the sets of possible configuration parameters  34  based on user-supplied information  30 , and relevant configuration conventions  16  from the configuration conventions data store  18 . In many cases, the users email address provides sufficient information to be able to generate an accurate set of configuration parameters. In the example embodiment, given the email address “jane.doe@foo.com”, the module  32  would use the configuration conventions  16  to generate the possible configuration parameters  34  “jdoe” for the login name, and “mail.foo.com” for the server name. 
     Email providers use many conventions when determining configuration parameters, and as a result, the module  32  generates many sets of possible configuration parameters  34 . To reduce the number of sets generated, the module  32  may only generate a subset of the sets of possible configuration parameters  34  based on additional user information, or based on heuristics of likelihood  33  that a given set of configuration parameters  34  may be successful under a given scenario. In an example embodiment, the user may indicate that only configuration conventions  16  with a protocol expression  39  of “IMAP” should be considered. In the example, the heuristics  33  could include tracking statistics about the number of attempts and percentage of successes using a given configuration convention  16 , and thereby only generate possible configuration parameters  34  based on this configuration convention  16  if certain conditions are met. 
       FIG. 6  is a flowchart illustrating an example of a method of guessing possible configuration parameters  34  for configuring access to the users mailbox. In step  40 , the module  32  receives user configuration information  30 . In step  42 , the module  32  retrieves relevant configuration conventions  16  from the configuration conventions data store  18 . In step  44 , the module  32  generates sets of possible configuration parameters  34  based on the configuration conventions  16  and the user supplied information  30 . In this step  44 , the module  32  would typically only generate a subset of the possible configuration parameters  34  by using either heuristics of likelihood  33  that a set of configuration parameters  34  would be valid, or by using additional user supplied information  30 . 
     It should be understood that the system and method for guessing configuration parameters, according to -one aspect of the present invention, may be applied to configuration parameters for services other than mailbox access. 
     Although many email providers adhere to fairly standard conventions for configuration parameters, such as naming the mail host “mail.&lt;MailDomain&gt;” and matching the login name to the email address, there are many other email providers that employ less obvious conventions, such as setting the login name to be &lt;FirstName(1)&gt;&lt;LastName(3)&gt;, which in the case of the user with e-mail address of “john.smith@foo.com” would translate to the login name of “jsmi”. In the case of protocols that use uniform resource locators (URL) to indicate the location of the mailbox, the conventions are even less standard, since the login names are often embedded in the middle of the URL. 
     By capturing these conventions in the data store, it is possible for the service that requires access to the user&#39;s mailbox to use the conventions to generate potentially valid sets of configuration parameters, and then attempt to determine a valid set of configuration parameters that can be used to access the user&#39;s mailbox. Therefore, it is possible to determine the set of configuration parameters for the user&#39;s mailbox even if the user is unable to provide all of the necessary configuration information. All that may be required from the user is an email address and password, from which the system may be able to successfully determine the configuration parameters in most cases. As new conventions are introduced or are discovered, they may be easily added to the data store. 
     In one aspect of the present invention, the configuration parameters are represented using symbolic expressions, which may then be retained in the configuration conventions data store  18  for use by the service. This allows the service to draw configuration conventions from the data store, and using context data, to construct a valid set of configuration parameters that can be used to access mailboxes. 
       FIG. 7  illustrates an example of a system of the present invention for generating configurations that comprise sets of configuration parameters  54 . A transformer module  52  as part of server  11  takes configuration conventions  16  stored in a configuration conventions data store  18  and expands them to generate configuration parameters  54  based on user supplied context data  50 . 
       FIG. 8  shows further details of the symbolic representation of configuration conventions  16 . The configuration conventions  16  symbolically represent the conventions used by email providers for a set of configuration parameters. The configuration conventions  16  comprise expressions  39  that represent individual configuration parameters using symbols  57 . In an example embodiment, the configuration convention  16  may be formed as an expression for the server name parameter, an expression for the login name parameter, and an expression for the mail protocol. If, in the example embodiment, the email provider uses the login name “jsmi” and the mail domain “mail.foo.com” given an email address “john.smith@foo.com”, the login name expression in the configuration convention  16  may be “&lt;FirstName(1)&gt;&lt;LastName(3)&gt;”, while the server name expression may be “mail.&lt;MailDomain&gt;”. In this example, the number in brackets within the symbol  57  “&lt;FirstName(1)&gt;”, represents the number of characters to be used from the users first name parameter, i.e., “j”. Similarly, the number in brackets in a symbol  57  “&lt;LastName(3)&gt;” represents the number of characters to be used from the users last name, ie. “smi”. As is obvious to one skilled in the art, a variety of different symbolic representations may be used to represent the conventions for configuration parameters. The choice of expressions  39  can be quite arbitrary, and are only limited by the requirement that the expression  39  can be expanded into a configuration parameter based on the context data  50  supplied to the transformer module  52 . 
     The configuration conventions data store  18  stores the configuration conventions  16 . As new conventions are introduced or discovered, they may be easily added to the configuration conventions data store  18 . 
     The transformer module  52  expands the individual expressions  39  into configuration parameters by expanding each symbol  57  into its corresponding value using context data  50 . In an example embodiment, a configuration convention  16  may comprise the mail protocol expression  39   a,  “POP”, the server name expression  39   b  “mail.&lt;MailDomain&gt;” and the login name expression  39   c  “&lt;FirstName(1)&gt;&lt;LastName(3)&gt;”, for example, as shown in  FIG. 5  for a plurality of expressions. If the transformer module  52  were provided with the context data  50  comprising the email address “john.smith@foo.com”, the transformer module  52  would infer the mail domain as “foo.com” from the email address. It would then generate the configuration parameters  34  of “POP” for the mail protocol, “mail.foo.com” for the server name, and “jsmi” for the login name. 
       FIG. 9  is an example of a flowchart illustrating a method of generating configurations by expanding expressions  39  using context data  50 . In step  60 , the transformer module  52  receives context data  50 . In step  62 , the transformer module  52  infers the mail domain for the users mailbox, and retrieves the relevant configuration conventions  16 . In step  64 , the transformer module  52  expands the symbols  57  within the expressions  39  of the configuration convention  15  using the context data  50 , to generate configurations that are formed by sets of configuration parameters  54 . 
     An exemplary hand-held mobile wireless communications device  1000  that can be used in the present invention is further described in the example below with reference to  FIG. 10 . The device  1000  includes a housing  1200 , a keyboard  1400  and an output device  1600 . The output device shown is a display  1600 , which is preferably a full graphic LCD. Other types of output devices may alternatively be utilized. A processing device  1800  is contained within the housing  1200  and is coupled between the keyboard  1400  and the display  1600 . The processing device  1800  controls the operation of the display  1600 , as well as the overall operation of the mobile device  1000 , in response to actuation of keys on the keyboard  1400  by the user. 
     The housing  1200  may be elongated vertically, or may take on other sizes and shapes (including clamshell housing structures). The keyboard may include a mode selection key, or other hardware or software for switching between text entry and telephony entry. 
     In addition to the processing device  1800 , other parts of the mobile device  1000  are shown schematically in  FIG. 10 . These include a communications subsystem  1001 ; a short-range communications subsystem  1020 ; the keyboard  1400  and the display  1600 , along with other input/output devices  1060 ,  1080 ,  1100  and  1120 ; as well as memory devices  1160 ,  1180  and various other device subsystems  1201 . The mobile device  1000  is preferably a two-way RF communications device having voice and data communications capabilities. In addition, the mobile device  1000  preferably has the capability to communicate with other computer systems via the Internet. 
     Operating system software executed by the processing device  1800  is preferably stored in a persistent store, such as the flash memory  1160 , but may be stored in other types of memory devices, such as a read only memory (ROM) or similar storage element. In addition, system software, specific device applications, or parts thereof, may be temporarily loaded into a volatile store, such as the random access memory (RAM)  1180 . Communications signals received by the mobile device may also be stored in the RAM  1180 . 
     The processing device  1800 , in addition to its operating system functions, enables execution of software applications  1300 A- 1300 N on the device  1000 . A predetermined set of applications that control basic device operations, such as data and voice communications  1300 A and  1300 B, may be installed on the device  1000  during manufacture. In addition, a personal information manager (PIM) application may be installed during manufacture. The PIM is preferably capable of organizing and managing data items, such as e-mail, calendar events, voice mails, appointments, and task items. The PIM application is also preferably capable of sending and receiving data items via a wireless network  1401 . Preferably, the PIM data items are seamlessly integrated, synchronized and updated via the wireless network  1401  with the device user&#39;s corresponding data items stored or associated with a host computer system. Communication functions, including data and voice communications, are performed through the communications subsystem  1001 , and possibly through the short-range communications subsystem. The communications subsystem  1001  includes a receiver  1500 , a transmitter  1520 , and one or more antennas  1540  and  1560 . In addition, the communications subsystem  1001  also includes a processing module, such as a digital signal processor (DSP)  1580 , and local oscillators (LOs)  1601 . The specific design and implementation of the communications subsystem  1001  is dependent upon the communications network in which the mobile device  1000  is intended to operate. For example, a mobile device  1000  may include a communications subsystem  1001  designed to operate with the Mobitex™, Data TAC™ or General Packet Radio Service (GPRS) mobile data communications networks, and also designed to operate with any of a variety of voice communications networks, such as AMPS, TDMA, CDMA, PCS, GSM, etc. Other types of data and voice networks, both separate and integrated, may also be utilized with the mobile device  1000 . 
     Network access requirements vary depending upon the type of communication system. For example, in the Mobitex and DataTAC networks, mobile devices are registered on the network using a unique personal identification number or PIN associated with each device. In GPRS networks, however, network access is associated with a subscriber or user of a device. A GPRS device therefore requires a subscriber identity module, commonly referred to as a SIM card, in order to operate on a GPRS network. 
     When required network registration or activation procedures have been completed, the mobile device  1000  may send and receive communications signals over the communication network  1401 . Signals received from the communications network  1401  by the antenna  1540  are routed to the receiver  1500 , which provides for signal amplification, frequency down conversion, filtering, channel selection, etc., and may also provide analog to digital conversion. Analog-to-digital conversion of the received signal allows the DSP  1580  to perform more complex communications functions, such as demodulation and decoding. In a similar manner, signals to be transmitted to the network  1401  are processed (e.g. modulated and encoded) by the DSP  1580  and are then provided to the transmitter  1520  for digital to analog conversion, frequency up conversion, filtering, amplification and transmission to the communication network  1401  (or networks) via the antenna  1560 . 
     In addition to processing communications signals, the DSP  1580  provides for control of the receiver  1500  and the transmitter  1520 . For example, gains applied to communications signals in the receiver  1500  and transmitter  1520  may be adaptively controlled through automatic gain control algorithms implemented in the DSP  1580 . 
     In a data communications mode, a received signal, such as a text message or web page download, is processed by the communications subsystem  1001  and is input to the processing device  1800 . The received signal is then further processed by the processing device  1800  for an output to the display  1600 , or alternatively to some other auxiliary I/O device  1060 . A device user may also compose data items, such as e-mail messages, using the keyboard  1400  and/or some other auxiliary I/O device  1060 , such as a touchpad, a rocker switch, a thumb-wheel, or some other type of input device. The composed data items may then be transmitted over the communications network  1401  via the communications subsystem  1001 . 
     In a voice communications mode, overall operation of the device is substantially similar to the data communications mode, except that received signals are output to a speaker  1100 , and signals for transmission are generated by a microphone  1120 . Alternative voice or audio I/O subsystems, such as a voice message recording subsystem, may also be implemented on the device  1000 . In addition, the display  1600  may also be utilized in voice communications mode, for example to display the identity of a calling party, the duration of a voice call, or other voice call related information. 
     The short-range communications subsystem enables communication between the mobile device  1000  and other proximate systems or devices, which need not necessarily be similar devices. For example, the short-range communications subsystem may include an infrared device and associated circuits and components, or a Bluetooth™ communications module to provide for communication with similarly-enabled systems and devices. 
     It will be appreciated that the above description relates to preferred embodiments by way of example only. any variations on the systems and methods described above will be obvious to those knowledgeable in the field, and such obvious variations are within the scope of the invention as described, whether or not expressly described. 
     For example, the system and method for learning and guessing configuration parameters may be applied to configuration parameters for services other than mailbox access. Symbolic expressions could be used to represent conventions for configuration parameters for services other than email and mailbox access.
