Description:
BACKGROUND 
       [0001]    The present invention, in some embodiments thereof, relates to messaging management and, more specifically, but not exclusively, to real time messaging management when a plurality of messaging protocols are available. 
         [0002]    During the last years, many messaging protocols have been developed. Session participants uses electronic mails, instant messaging (IM) messages, chat messages, Short Message Service (SMS) messages, and the like in order to communicate with one another. 
         [0003]    As SMS messages, email messages and IM messages are fundamentally symmetric forms of communication, once someone sends a recipient an SMS, for example, then the normal way of responding is with a reply SMS. Using different forms of communication leads forces session participants to use forms of communication which they do not master or do not like. An inability to reply in a preferred manner may be frustrating for session participants and may lead to a lost revenue opportunity for telecoms operators.

     DETAILED DESCRIPTION 
       [0035]    The present invention, in some embodiments thereof, relates to messaging management and, more specifically, but not exclusively, to real time messaging management when a plurality of messaging protocols are available. 
         [0036]    According to some embodiments of the present invention there are provided methods and systems of managing multi participant (two or more) session wherein session participants can communicate with one another using a user selected application (i.e. clients or software) of any of a plurality of different messaging protocols, for example IM protocol and email protocol. In such a manner, a user who prefers sending and receiving message content using email protocol can send emails which are received as IM messages by a recipient that prefers receiving message content using IM protocol, for instance using an IM application that is installed on his device, and vice versa. 
         [0037]    Optionally, the methods and systems support the generation of message summary that allows a user to catch up with session messages which have been held without him by other participants of the multi participant session, for instance between users of IM protocol clients where he is set to receive email messages only. 
         [0038]    Optionally, the methods and systems support updating an email user about a current inputting of data by an IM user who is also a participant of a multi participant session. 
         [0039]    Optionally, the methods and systems provide a policy based solution that adapts the distribution of media content of messages for providing seamless and continuous experience in a messaging protocol hybrid mechanism, allowing session participants who use different messaging editors (and protocols) to communicate with one another in a preferred manner without installing new client software and/or adapting existing user interfaces of currently used messaging editors. 
         [0040]    Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways. 
         [0041]    As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method or computer program product.

The program code may execute entirely on the session participant&#39;s computer, partly on the session participant&#39;s computer, as a stand-alone software package, partly on the session participant&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the session participant&#39;s computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). The implementation of software modules may reside on one or more clients, one or more servers, or on any combination thereof. Servers implementation might reside on a local service provider network, on a remote cloud, software as a service provider or any combination thereof. Any of the described Clients might be implemented as a local module or through a web browser to a remote module. 
         [0046]    Aspects of the present invention are described below with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. 
         [0047]    These computer program instructions may also be stored in a computer readable medium that can direct a computer, other programmable data processing apparatus, or other devices to function in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the function/act specified in the flowchart and/or block diagram block or blocks. 
         [0048]    The computer program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other devices to cause a series of operational steps to be performed on the computer, other programmable apparatus or other devices to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide processes for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. 
         [0049]    Reference is now made to  FIG. 1 , which is a flowchart  100  of a method establishing multi participant communication session among participants who use different messaging protocols for sending media content, for example using IM client module applications and email client modules, according to some embodiments of the present invention. The method allows sending textual, audible, or visible content to one or more recipients such that each recipient receives the media content via a recipient preferred messaging protocol selected from a plurality of different messaging protocols. 
         [0050]    As used herein, a messaging protocol may be an electronic mail (email) protocol, an instant messaging (IM) protocol, a cellular messaging protocol, such as a short message service (SMS) or a multimedia messaging service (MMS), and/or the like. 
         [0051]    As used herein, an IM protocol includes any chat facilitating messages which distribute media messages in real time (RT) as part of a communication messaging session creating a synchronous flow of messages, for instance a chat, a hangout, or a data sharing process, such as co browsing. As used herein, media content may be image content, textual content, video content, audio content and/or the like. IM protocol may be, for example, Mumble, Gadu-Gadu™, IRC™, Windows Live Messenger™ (MSNP), OSCAR™ (AIM,ICQ), RVP (Windows Messenger™), SIP/SIMPLE™, Skype™ Steam Friends™, TOC2™, Windows Messenger service™, OMA-IMPS, RCS, XMPP/Jingle (Google Talk™), YMSG (Yahoo! Messenger™), and Zephyr Notification Service™. Email protocol may be, for example, point of presence (POP), for example POP3, internet message access protocol (IMAP), message application programming interface (MAPI), and HTTP, and simple mail transport protocol (SMTP). 
         [0052]    The method allows establishing a messaging session among a plurality of session participants who use different messaging protocols during the messaging session, optionally subscribers. As used herein, a messaging protocol describes a protocol and supporting system(s) for exchanging messages among session participants. For example, a messaging protocol may be an email protocol, indicating that an email client module is used to send and/or receive an email sent via email server and/or services. In another example, a messaging protocol may be an IM protocol, indicating that an IM client module is used to send and/or receive an IM message over a communication network, such as the internet, for instance using an IM and presence server (see  210  in  FIG. 2 ). In another example, a messaging protocol may be a cellular messaging protocol, indicating that a cellular messaging client, for instance an SMS, is used to send and/or receive SMS messages over a cellular network. For brevity, IM messages cover SMS messages. The method allows the participants to exchange messages with using different messaging protocols using their favorite editor, for instance using their email client module for communicating with participants who use IM client modules and participants who use SMS editors and/or other email client modules. 
         [0053]    Reference is also made to  FIG. 2 , which is a schematic illustration a system  200  for establishing and/or managing messaging sessions, for instance by implementing the method depicted in  FIG. 1 , according to some embodiments of the present invention. From the user experience point of view, for example as depicted in the flowchart of  FIG. 3 , the system and method allow one participant (i.e. participant A;  501 ) to send other participant emails (i.e. participants B and C;  502   503 ) and one of the participant to reply with an IM message (i.e. participant B;  504 ) where the reply is received at one participant as an IM message  505  and in another participant as an email  506 . Another participant may send an email using his email client module (i.e. participant C;  507 ) and the content may be received at other participants via an email client module and an IM client module (i.e. participants B and A;  508   509 ). With regards to  FIGS. 3-6 , it should be noted that horizontal arrows depict message sending events, elliptical text bubble indicate message reception events or action states (when the bubble is not filled), vertical arrows indicate a timeline, dotted filling indicates an IM protocol action, and stripped filling indicates an email protocol action. 
         [0054]    The system  200  may be a policy based system that adapts the distribution of media content of messages for providing seamless and continuous experience in a messaging protocol hybrid system that allows session participants who use different messaging editors (and protocols) to communicate with one another in a preferred manner. For example, the system  200  allows first session participants who prefer receiving and sending emails using an email client module to communicate with second session participants who prefer receiving and sending IM messages using an IM client module while the first session participants use email client modules, such as Microsoft Outlook™, Thunderbird™, Gmail™ or Apple Mai 1 ™, optionally at the same manner the email client modules are used for receiving and sending emails and the second session participants use IM client modules, such as WhatsApp™ or Line™, optionally at the same manner the IM client modules are used for receiving and sending IM messages. 
         [0055]    The system  200  offers real time (RT) integration of IM client module session participants in a messaging session that is held among email session participants without sacrificing the ability of email session participants to communicate with other participants, for example by adding email recipients to an ongoing messaging session and/or real time (RT) integration of email client module session participants in a messaging session that is held among IM session participants without sacrificing the ability of IM session participants to communicate with other participants, for example by adding IM recipients to an ongoing messaging session. 
         [0056]    Optionally, the system  100  manages the distribution of message content among a plurality of recipients such that some recipients receive the message content encoded as email content and some recipients receive the message content encoded as an IM message. This also allows each one of the recipient to respond to the received message content via the messaging protocol they prefer, optionally in a seamless manner to the other recipients who may not be able to know which editor and/or messenger the senders use. 
         [0057]    The system  200  includes a processor based network node, such as one or more managing servers  201 . The one or more managing servers  201  include one or more computerized processor(s)  202 , such as central processor unit(s) and a routing module  203  that forwards message content based on user preference profile and/or system logic. The system  200  may include a user preference profile module  204  that manages a plurality of session participant preferences profiles stored in a repository (i.e. database)  205 , either locally or remotely, and for instance as described below. 
         [0058]    Optionally, the system  200  includes a spam filter  211  which reviews message content to prevent from IM session participants to receive spam messages from email accounts and/or email session participants to receive spam messages from IM accounts. The spam filter may be internal or provided by an external service to which messages are forwarded for analysis. Optionally, the system includes a throttling module  212 , which applies decision logic as to which messaging protocol to use and when and/or how to filter and/or amend sent messages. The logic is optionally based on the user preference modules. For example, the throttling module  212  may decide when to send emails or IM messages based on time, number of aggregated messages, accumulated size of messages and/or other parameters. The throttling module  212  may send emails using the original address of the sender, for example using credentials which are received as described below, or as using a special addressing of the system. The special address of the system may be formed such that when a session participant replies to a message from this address, the reply is distributed to all other session participants. 
         [0059]    The system  200  may include one or more messaging client modules  207  which may be installed on client terminal  206  such as laptops, desktops, Smartphones, tablets, smart glasses, and/or any other user controlled computing unit. It should be noted that the messaging client modules  207  may be implemented using cloud technologies, for example as browser based clients having a graphical user interface (GUI) presented to a user using the client terminal  206 . In such embodiments, all or some of the functions of the messaging client modules  207  which are described herein are performed by the routing module  203 . The routing module  203  is supported by the processing unit(s)  202  and/or any other centralized or distributed computing units (for example any processor not logically controlled by the operating system of the client terminals  206 ). The system  200  may include a mail server module  208  that is installed in a mail server  209 , for example in a simple mail transfer protocol (SMTP) server for editing sent emails, for example by adapting email relay, for instance during an SMTP relay. 
         [0060]    As depicted by numeral  207 , the messaging client modules  207  may be installed in the client terminals  206  themselves, for instance as applications, personal information management software add-ons, for example Outlook™ add-ons, browser add-ons, integral part of messaging software, for example product, an e-mail information management software product and/or the like. Optionally, the messaging client modules  207  include an IM client module for allowing the client to generate IM messages. Optionally, the messaging client modules  207  are integrated into existing IM client modules. Optionally, the messaging client module  207  is integrated into an email client module and into an IM client module which are independent from one another. Optionally, the messaging client module  207  includes both an email client module and an IM client module. In such embodiments, the messaging client module  207  manages dual stacks for email messages and IM messages. This messaging client module  207  is able to send/receive emails and be engaged with IM communication. Although those two streams may come from different servers and/or sources, the messaging client module  207  may merge them to one coherent and ordered view. 
         [0061]    As depicted in  101 , the system  200 , for example the user preference profile module  204  manages a plurality of user preference profiles where each user preference profile defines for one of a plurality of session participants, for example a subscriber of the system  200 , a preferred messaging protocol. The preferred messaging protocol may be selected from an electronic mail (email) protocol, an instant messaging (IM) protocol, and a cellular messaging protocol. The user preference profile may include one or more record(s) which define a preferred communication protocol of a session participant, optionally in predefined conditions. For example, a user preference profile may define a default preferred communication protocol of a session participant, rules for when to use one communication protocol or another, and/or a hierarchy of preferred communication protocols which are available for usage. In another example, different preferred communication protocols are set for different times of the day and/or of the week. In another example, different preferred communication protocols are location based, for example using locational data of the hosting client terminal(s)  206 . In another example, different preferred communication protocols are event based, for example depend on event of the application(s) the hosting client terminal(s)  206  such as online status of the recipient (e.g. online recipient will get an IM, while offline recipient will receive an email). In such embodiments, when the user is indicated as being in a meeting, for example based on an analysis of the schedule of the user, a designated preferred communication protocol is selected. In another embodiment, a designated preferred communication protocol is selected when the user uses the client terminal for talking and/or for performing another function. 
         [0062]    Now, as shown at  102 , a message having media content provided by a session participant, for example an email or an IM message, is intercepted at the sender side, for example by the messaging client and/or the mail server client  208 . This content may be referred to herein as message content. The message may designate one or more recipients. Optionally, the media content is a message created using a standard email client module on a client terminal  206 . 
         [0063]    Optionally, the message is analyzed to determine whether is designated to be handled by the system  200 . For example, an indicator, also referred to herein as a marker, is added to system, for instance a flag and/or any other label. The marker is added to the metadata and/or to the body of the message. If the message marked as designated to be handled by the system  200 , it distributed according to the system logic, for example as described below and if the message marked as designated not to be handled by the system  200 , it is forwarded as is from the sender side. 
         [0064]    Optionally, the marker is an identifier added to the header of a message, for example to a Proprietary E-Mail header. Optionally, the message-ID is formatted to include a unique prefix as a marker. For example, the unique prefix is numeric where the value “2” indicates that the message is handled by the system  200 . Optionally, a unique string is added to the message ID, for example, string Message ID may be added with a literal prefix “Mix-Mode” that does not appear in other messages. Optionally, headers are adapted when message(s) are sent using reply or reply all functions. Optionally, body of the message is adapted to include a marker. Optionally, an object is embedded in a message as a marker, for example a web bug. Optionally, metadata is updated with a marker. 
         [0065]    Optionally, the messaging client module  207  reviews the received emails, identifies markers, and notifies the managing server(s)  201  accordingly. The managing server(s)  201  may use push notification such as internet message access protocol (IMAP) IDLE to intercept emails and identify specific markers such as the mix-mode identifiers which are described below. In such embodiments, the system  200  may extract stored IM messages that were not delivered to some session participants and send the IM content of these IM messages in one or more email messages. As described below, these emails are manipulated to precede in time the intercepted email message (most email clients order received emails by time and thus context of the email correspondence timeline is kept. Optionally, the managing server(s)  201  may use periodic fetch and/or polling mechanism for acquiring data from messaging client modules  207 . After receiving notifications about the reception of messages at the messaging client module  207 , the managing server(s)  201  may instruct the deletion of redundant messages (i.e. summarized in a summary message or sent twice, via email and IM). As described above, the managing server(s)  201  may send summary messages, update availability status and/or adjust (tweak) time tags as described below. 
         [0066]    Optionally, the messaging client module  207  deletes message upon receipt. Optionally, push server(s) may support this extension so that offline clients do not receive the email. 
         [0067]    Now, as shown at  103 , one or more recipients of the message are identified at the sender side. For example, the message is an email and the one or more recipients are extracted from the “TO” field(s) and/or from the “RCPT TO” field at the sender side. 
         [0068]    This allows, as shown at  104 , a messaging protocol to be selected for each recipient. For example, during the process it is identified which of the recipients is interested in receiving content message in an email and which of the recipients is interested in receiving content message in an IM message. For instance, records of recipients are identified in user preference profiles stored in the repository (i.e. database)  205 . These records allow selecting a preferred messaging protocol for each recipient. These records may be accessed or acquired by querying the user preference profile module  204 . 
         [0069]    Additionally or alternatively, a local policy may be maintained at the client side to determine which messaging protocol to use for each one of the recipient. This may be determined by local logic or database. 
         [0070]    Additionally or alternatively, a supplementary policy server and/or registry and/or directory and/or database and/or dynamic service and/or external network resources is consulted for selecting messaging protocols. 
         [0071]    Additionally or alternatively, a mechanism in which a sender attempts to send an IM to one or more recipients and the system fails to deliver the IM, for example when no acknowledge is identified, an email protocol may be selected and email may be sent by the respective messaging client module and/or a different routing is selected for the IM message by the managing module  203 . 
         [0072]    Additionally or alternatively, the client messaging module  206  may be aware and/or present an updated status for each participant in a messaging session and/or other system users prior to and/or during a composition of a message and/or when a desire to compose a message is identified, for instance by addressing a contact list, phonebook, and any other mention of a contact name, for instance in a document or by giving voice instructions. Example for such a status might be to indicate availability to communicate and/or a preferred protocol “IM capable” or “Email capable”. 
         [0073]    Optionally, session participant provides email credentials, for example using a UI, to allow the system  200  to perform actions on behalf of the participant&#39;s email account. Such actions may include the ability to control the sender address for automatically sending different messages such as invite to download the IM client module, invite to register to the system, and invite to use a web client module. These credentials may be used for sending summary messages as described herein. 
         [0074]    Additionally or alternatively, a list of recipients and their preferred messaging protocols is embedded inside the body of the message, indicating the user that a Reply-To-All is needed and disclosing all recipients of such action. 
         [0075]    Optionally, the list is embedded inside a “To: recipient address” display, so “To address” have only E-Mail recipients, but their display name mismatch them and identifies all. 
         [0076]    Additionally or alternatively, addresses of the recipient are replicated, for example Bob@gmail.our-domain.com is created for Bob@gmail.com. In use, recipients may be deduced from the replica addresses. This allows a relay on a different domain to catches the email and to send and/or to reply-to-all and/or to handle the email well. 
         [0077]    Optionally, the routing module gathers IM content from IM messages sent among session participates of a certain messaging session and generates accordingly a summary message, optionally periodically in iterations, for instance every 1 minute, 5 minutes, 10 minutes, 15 minutes and/or any intermediate or longer periods. The summary message is sent to other session participates of the messaging session, optionally periodically in iterations, for instance every 1 minute, 5 minutes, 10 minutes, 15 minutes and/or any intermediate or longer periods. This allows the other participants, for example participants selected to receive messages via an email client only, to catch up with session messages which have been held without them during the multi participant session, for instance between users who preferred using IM protocol clients. 
         [0078]    Reference is now made to  105 ,  106  and  120  which depict optionally functionalities for treating an email at the sender side (either a client module or an email server module). 
         [0079]    Optionally, if the message is an email, as shown at  105 , it is formatted, at said sender side, so that it sent in an SMTP delivery only to recipients who have been identified as session participants who currently prefer the email protocol as a preferred protocol. The media content is forwarded to other session participants via the protocols they have selected, using the messaging client module  207  or the mail server client  208  or the one or more managing servers  201 , for instance the routing module  203 . 
         [0080]    For example, as described above, a list of recipients is identified by an analysis of the “TO” field(s). Then, the mail server client  208  and/or the messaging client module  207  formats the “RCPT TO” field(s) in the email to include only the session participants who currently prefer the email protocol as a preferred protocol, removing session participants who currently prefer other messaging protocols as a preferred protocol. Optionally, the SMTP stack is modified to break the symmetry between the “TO” field(s) and the “RCPT TO” field(s) in the email. In such a manner, session participants who currently prefer other messaging protocols, for example the IM protocol, will not get the email; however, the email addresses of the session participants who currently prefer other messaging protocols remains in the “TO” field(s) such that if any of the email recipients will send an email using a “reply to all” function, they will receive it. Leaving all original recipients in the “TO” field(s) ensure transparency and messaging session continuity. 
         [0081]    It should be noted that when the message is an email, it may only be formatted and not resent via another address, the sent email is identified as an email from the creator of the media content it contains and not as an email from a server or a proxy and therefore will not be classified as a spam based on its origin. One reason to implement this is in order for the recipient to trust the sender. 
         [0082]    Optionally, if the message is an IM, as shown at  106 , it is forwarded to session participants who have been identified as session participants who currently prefer the IM protocol as a preferred protocol and forwarded to an email server, at the sender side, so that it sent as an email, for example in an SMTP delivery, to session participants who have been identified as session participants who currently prefer the email protocol as a preferred protocol. 
         [0083]    As described above, the list of recipients is analyzed to determine which messaging protocol should be used for each recipient where the messaging protocols are selected according to the user preference profiles of the recipients (i.e. participants of the messaging session). When a recipient is not associated with a user preference profile, for example not a subscriber of the system  200 , his address, as specified in the sent message, is used for sending a link or any other reference for downloading the messaging client module  207 , installing the mail server module  208 , and/or registering to the system  200 . The address may be, for example, an email, an IM identifier, and/or a phone number. 
         [0084]    Optionally, the system  200  logs the media content of messaging sessions which include message formatted and/or distributed thereby. In such embodiments, when a participant of the messaging session is subscribed or otherwise joins the system  200 , for example by installing the client  207 , the system  200  can forward the previous media messages of the messaging session to him, for instance as a summary, a transcript, and/or the like, either as a separate message or with the next message of the messaging session. For example,  FIG. 4  is schematic illustration of a flowchart depicting a flow of messages in an exemplary messaging session, according to some embodiments of the present invention. In this exemplary messaging session, as shown at  601 , session participant A sends an email message. The system  200  identifies that session participants B and C are registered and session participant D is unregistered to the service. Session participants B and C receive an IM message with the message content from session participant A, for instance a copy of the email content in an IM message. Session participant D receives the message content from session participant A in an email with a link for downloading the messaging client module  207 . This may be enabled with a web client and/or hypertext markup language, such as HTML 5  widget, a JavaScript implementation, add-on to browser and alike. The messaging client module  207  enables session participant D to experience an RT experience while using an email, for example by modifying messaging session related emails to include the previous messages of the messaging session. 
         [0085]    Optionally, a message that includes a reference or a link (e.g. as shown at  601 ) to install the messaging client module  207  and/or to register to the system  200  is deleted after installation or registration is completed, for instance by the messaging client module  207  and/or the mail server module  208 . 
         [0086]    Optionally, a message that includes a reference or a link to a web client module. The web client runs at the context of the Client terminal. The web client may provide IM functionality to supplement email client modules, without the need to download and install the IM client module. 
         [0087]    According to some embodiments of the present invention, a plurality of message copies of a message is sent to a plurality of the recipients in a distribution list, optionally selected as above, where each copy includes a different unique reference or link to an external resource such as a web bug, for example a Universal Resource Identifier (URI), for instance a different Uniform Resource Locator (URL). This allows identifying a client, a recipient processing the unique reference or link. In such embodiments, while the mail server  209  sends N different copies with different links (N=number of unique recipients), only one copy is stored in the sent item folder of the sender. This allows identifying which recipient read the message and optionally when, for example by an icon which is presented near his name or address in the respective inbox and/or send item folder. 
         [0088]    Additionally or alternatively, code lines such as X-headers are added into email headers such as “X-Confirm-Reading-To:”; “Disposition-Notification-To:” or “Return-Receipt-To:” or as part of the SMTP protocol request. 
         [0089]    Additionally or alternatively, read-recipient report code may be added into the body of the copy to induce a read report non-selectively, for example when a client module is installed and/or when the email is read by a browser client (e.g. using an toolbar add-on and/or a script). 
         [0090]    According to some embodiments of the present invention, a read indication is presented not only to the sender but also to other recipient of the message. This may be performed as if each of the recipients is the sender, for example as described above. Read indications may be sent to the messaging client  207  and/or respective module which generates a browser based presentation. Another option would be for the sender client to re-distribute the read indication to other recipients of the message after it the read indication has been received. 
         [0091]    As shown at  602 , session participant B now sends a chat message that is forwarded only to respective subscribers of the system  200  who are identified as preferring the IM protocol, namely session participant A and C. The message is not forwarded to session participant D. After participant D activates the system  200 , as shown at  603 , for example by installing the messaging client module  207 , an history email or an history IM message with previous correspondences (related to the respective messaging session) is forward thereto  604 , for instance in an IM message. Optionally, the email with the link is deleted from the “Sent Items” folder of the sender and/or the inbox of the recipient to avoid redundancy. As shown at  605 , now, when participant C sends an IM message, it is received by all participants. 
         [0092]    Another example is depicted in  FIG. 5  which is a schematic illustration of a flowchart depicting a flow of messages in another exemplary messaging session, according to some embodiments of the present invention. In this example, session participant A sends an IM message to session participants B, C, D, E (for example by designating email addresses) where session participant D is not registered and did not install the messaging client module  207  Therefore session participant D does not receive the IM message as long as he does not install the messaging client module  207  or register. In addition, participant E is registered to system  200  with user preference profile which directs to get an email at this specific time (according to time-based policy). 
         [0093]    According to some embodiments of the present invention, the time tags of messages, for example emails, such as system generated emails which include a summary of the previous historical session related messages is adapted such that it appears as sent before other email(s) of the session. In such a manner, the timeline in which messages of the sessions is presented in the inbox of the recipient(s) corresponds with the actual timeline of the transmission and/or reception of the messages. 
         [0094]    As described above, messages are optionally marked with a marker indicating they are messages handled and/or set to be handled by the system  200 .  FIG. 6  is a schematic illustration of a flowchart depicting a flow of messages in another exemplary messaging session where a message is sent with a marker, according to some embodiments of the present invention. As shown at  701 A, session participant A sends an IM to participants B and C and as shown at  701 B email with reference to join the system  200  and a marker, a Mix-Mode identifier to participants D and E. As shown at  702 , participant B replies by IM message sent to all session participants. Participants A and C get IM, participant D receives nothing, and participant E has a user preference profile which includes policies to receive email only at this time and no throttling. As shown at  703 , at a later time (e.g. 16:00), session participant D sends an email to all session participants, for instance by using reply all function on his email client module. The email is marked with a marker indicating it is part of the session. The email is intercepted at the recipient side, for instance based on the marker, by the messaging client module  207  or the mail server module  208 . Consequently, as shown at  704 , the system  200  generates a summary message that includes an historical messaging summary, including the IM messages sent at  702 , (e.g. before 16:00). Optionally, the history message may be added to the email session participant D sends. Optionally, the history message is sent separately from the email session participant D sends. Optionally, the email session participant D sends is halt until the history message is sent. Optionally, as shown at  705 , time tag of the history message and/or of the email which induces the sending of the summary message is tweaked to a previous time before the email session participant D sends, in order to maintain the messaging session order. 
         [0095]    It should be noted that emails which are treated by the system  200  are marked with a marker, a summary may be generated and sent to some participants. Additionally or alternatively, marked messages may be deleted after summary email is sent. 
         [0096]    As described above, the system  200  and method  100  allow email users to receive message content inputted using an IM client module and sent originally as an IM message in a seamless manner. According to some embodiments of the present invention, an indication which indicates to one session participant that another session participant is currently inputting message content is presented on an email client module. This indication maybe referred to herein as an “is writing a message” (IWAM) indication. In such a manner, a session participant who selected the email protocol as a preferred protocol may receive notifications that session participants who selected the IM protocol as a preferred protocol and use an IM client module receives. Optionally, the messaging client module  207  includes an IWAM sub module that presents an indication on the screen of one session participant when another session participant inputs message content. For example, a JavaScript supporting email client module (limited today, may exist more in the future) allows the email to query a web server. Another example is an object, such as a graphics interchange format (GIF), attached to the message. This object is used to get dynamically the status of IM client modules used by other participants, for example from the IM and presence server  210 . The IM and presence server  210  may be also used for monitoring status of each session participant, for example as described below. In another example, every state change is sent as an email, captured by messaging client module  207  that presents the notification accordingly and optionally deletes the received email from the inbox of the recipient. Optionally, the messaging client module  207  includes an IWAM sub module that detects when a session participant input data to an email client module and forward the data so as to allow the presentation of a IWAM indication to session participants, for example on their email client module and/or IM client module. 
         [0097]    The methods as described above are used in the fabrication of integrated circuit chips.
