Here is info from MCI Mail help files on exchanging messages with ATT
Mail via the X.400 gateway. You may want to check the ATT Mail help
files for info on entering X.400 addresses on the ATT Mail system.
 
If you can get these instructions to your friend who is on MCI Mail, you
friend can than attempt to send you a message by following the MCI Mail
X.400 instructions. When you (hopefully) receive your friends message
you can check the "From:" line to see how your friends return address
looks on your system. If it works your home free. If it does not work
have your friend call the MCI Mail help desk and request assistance from
an X.400 specialist. I have hade similar difficulities but have always
been able to resolve them with a some effort and sometimes assistance
MCI Mail's customer service help desk.
 
                +--------------------------------------+
                |        Command:  HELP ATTMAIL        |
                +--------------------------------------+
 
        Now you can exchange electronic mail with US AT&T Mail
        subscribers and private systems connected to AT&T Mail. It's as
        easy as sending an MCI Mail message.
 
        And during the special introductory period, there is no
        additional charge.  You pay the same prices as for any MCI Mail
        Instant Letter.
 
        All you need to know is your AT&T Mail recipient's E-mail
        address.
 
        Type HELP X400 TERMS for an explanation of X.400 addressing
        terms.
 
        Type HELP ADDRESS ATTMAIL for details on addressing the envelope
        for an AT&T Mail recipient.
 
        Type HELP X400 RECEIVE for details on how to provide your AT&T
        Mail correspondents your MCI Mail address.
 
                +--------------------------------------+
                |  Command:  HELP ADDRESS ATTMAIL      |
                +--------------------------------------+
 
        Using X.400 addressing, you can exchange messages with AT&T Mail
        subscribers and private systems connected to AT&T Mail.
 
                  ------------------------------------
                   Addressing AT&T Mail Subscribers:
                  ------------------------------------
        To send a message to an AT&T Mail subscriber, you need to know
        your recipient's AT&T Mail address (also known as their O/R
        name). The best way to guarantee you have the correct
        information is to check with your correspondent.
 
        Generally, an X.400 E-mail address consists of a mail system
        name (ATTMail), the country in which the mail system operates
        (US), and a personal name (broken into Surname and Given name).
        MCI Mail does not require you to supply the Country, however.
 
        If the AT&T Mail subscriber has a fairly common name, you should
        include their AT&T Mail Username to ensure delivery.  The AT&T
        Mail Username is usually the person's first initial followed by
        their last name. See Note 1 for special instructions when
        including the AT&T Mail Username.
 
        Directions on how to address an AT&T Mail subscriber from MCI
        Mail follow.  Create your message and type your recipient's last
        name on the TO or CC line.  Type (EMS) following the name.  At
        the EMS prompt, enter ATTMail.  In the MBX lines that follow,
        type the rest of your AT&T Mail recipient's name. You must label
        the information you enter.  Place an equal sign between the
        label and the information. Note, there CANNOT be any spaces
        before or after the equal sign.
 
        The valid X.400 labels are:
 
        SU=Surname (or Last name)
        GI=Given name (or first name)
        IN=Initials
        GE=Generational Qualifier
        OR=Organization
        UN=Organization Unit
        PR=Private domain (PRMD)
        DDA=Domain-defined Attribute
 
        What you enter:
        (Note that few labels are required)
 
        CREATE
 
        TO:   Recipient's Last name   (EMS)
        EMS:  ATTMail
        MBX:  GI=Recipient's First name
        MBX:  (carriage return)
 
        --------------------------------------------------------------
        Note 1. Addressing an AT&T Mail subscriber by his/her Username:
        --------------------------------------------------------------
        When an AT&T Mail subscriber's name is not unique on AT&T Mail,
        it is necessary to supply his/her Username in the address.  This
        is done with a Domain Defined Attribute (DDA). The Username is
        entered in the MBX line and is preceeded by: DDA=ID= There
        cannot be any spaces between the equal sign and the AT&T Mail
        Username.
 
        What you enter:
 
        CREATE
 
        TO:   Recipient's Last name   (EMS)
        EMS:  ATTMail
        MBX:  GI=Recipient's First name
        MBX:  DDA=ID=Recipient's AT&T Mail Username
        MBX:  (carriage return)
 
        ---------------------------------------------------------
        Addressing Messages to X.400 PRMDs connected to AT&T Mail
        ---------------------------------------------------------
        To address a message to someone on a private mail system (PRMD)
        connected to AT&T Mail, enter the X.400 address information that
        the private system needs to deliver the message to your
        correspondent.  Check with your correspondent to determine which
        O/R name attributes (or components) are required to send him/her
        messages.
 
        A message to a private e-mail system (PRMD) connected to AT&T
        Mail is created the same way a message to a AT&T Mail subscriber
        is created.  Note that an additional X.400 component, the PRMD,
        is required and placed in an MBX line.
 
        What you enter:
 
        CREATE
 
        TO:    Recipient's Surname   (EMS)
        EMS:   ATTMail
        MBX:   PR=Recipient's mail system name
        MBX:   GI=Recipient's First name
        MBX:   OR=Recipient's Organization              Optional
        MBX:   (carriage return)
 
        If additional information is required
        to ensure delivery, be sure to enter
        it, appropriately labeled, in the MBX
        lines.
 
        ---------------------------------------------------------------
        Addressing Messages to AT&T Mail Remote Electronic Mail Systems
            (Non-standard Gateways)
        ---------------------------------------------------------------
        To address a message to someone on a remote mail system
        connected via a non-standard gateway to AT&T Mail, additional
        address information must be entered.  To ensure accuracy, check
        with your correspondent for their correct address.
 
        A message to an AT&T remote system is created in much the same
        way a message to a AT&T Mail subscriber is created.  Note that
        two additional addressing components are required. These are
        Organization and DDA.  They are labeled OR= and DDA= and are
        placed in an MBX line.
 
        What you enter:
 
        CREATE
 
        TO:    Recipient's Surname   (EMS)
        EMS:   ATTMail
        MBX:   GI=Recipient's First name
        MBX:   OR=Recipient's Organization
        MBX:   DDA=ID=System Path(b)USERNAME
        MBX:   (carriage return)
 
        For UNIX destinations -
 
        MBX: DDA=ID=<Unix System>(b)Username
 
        For PROFS destinations -
 
        MBX: DDA=ID=<PROFS System>(b)Username
 
        For 3780 destinations -
 
        MBX: DDA=ID=<3780 System>(b)Username

        What is your MCI Mail X.400 Address?
 
        X.400, the internationally approved standard for connecting
        electronic mail systems, has made possible the interconnection
        of MCI Mail and X.400-based private (corporate mail systems) and
        public electronic mail services.
 
        MCI Mail subscribers and connected systems may exchange E-mail
        messages with Telemail and AT&T Mail subscribers as well as
        private systems connected to Telemail and AT&T Mail.
 
        MCI Mail subscribers should provide their O/R names to the
        people with whom they wish to communicate. Generally, here is
        the information you should provide:
 
        ADMD           MCI
        Country        US
        Surname        Your last name (as registered on MCI Mail)
        Given name     Your first name (as registered on MCI Mail)
 
        If your name is fairly common, and the above information is not
        sufficient to uniquely identify you on MCI Mail, provide the
        following additional information:
 
        DDA  "ID" plus your unique MCI ID.  (See note 1 below.)
        Organization   Your organization.   (See note 2 below.)
 
        If your mailbox is not in the name of an individual, then the
        entire mailbox name should be considered the Surname.
 
        To find your MCI ID and Organization, type FIND NAME followed by
        your name.  Your name, MCI ID, and Organization - as registered
        on MCI Mail - will be displayed.
 
        O/R name example:
 
        This is the O/R name MCI Mail subscriber Tom Matthews should
        provide to those who wish to send him X.400 messages:
 
        ADMD       MCI
        Country    US
        Surname    Matthews
        Givenname  Thomas  (He is registered on MCI Mail as Thomas, not Tom.)
        DDA        ID=1234567   (His MCI Mail ID)
        
        Note 1 -- A Domain-defined attribute with your unique MCI Mail
        ID is the most accurate way to ensure that a message will be
        able to be delivered to your MCI Mailbox.  When you provide this
        information, tell your correspondent that they should use a DDA
        with a type ID and the value is your 7 digit MCI ID.
 
        Note 2 -- Organization sometimes helps identify a subscriber.
        However, you need to be very careful with this component.  If
        you did not register an organization at the time you registered
        your MCI Mail account, or you have changed your organization but
        not notified MCI Mail, do not use this component. If someone
        sends you a message and includes an incorrect (or partially
        correct) organization, the message cannot be delivered to your
        mailbox -- even if everything else is correct!
 
        Also note that MCI Mail does not use Organization Unit to
        identify MCI Mail subscribers.  Do not provide one to your
        correspondent.
 
        Type HELP X400 TERMS for more information on X.400 addressing
        terminology.

         In order to properly exchange messages with X.400 mail
         services, it is important to understand a little X.400
         addressing terminology.
 
         O/R Name is a common term.  It means originator/recipient name.
         It is made up of several components.  They are:
 
         ADMD - or Adminstrative Management Domain.  This is a public
         E-mail service.  MCI is an ADMD.  Telemail and AT&T Mail are
         also ADMDs.
 
         PRMD or Private Management Domain. This is a private -- usually
         a corporate -- electronic mail system that is connected via
         X.400 to an ADMD.
 
         Country - the country in which the domain (PRMD or ADMD) resides.
 
         Personal name is made up of the following 4 components:
          - Surname - a person's last name.
          - Given name - a person's first name.
          - Initials - a person's initial(s).
          - Generation Qualifier  - Jr., Sr. for example.
 
         Organization - the name of the organization to which a person
         belongs.
 
         Organizational Unit - the department or division of an organization.
 
         Domain-defined attribute (DDA) - a special field that helps the
         receiving system know how to deliver a message to the recipient.
 
         MCI has designed brief labels for each O/R name component.  Use
         these labels when addressing an X.400 recipient:
 
         Label      O/R name component
         PR         PRMD or Private Domain
         SU         Surname
         GI         Given name
         IN         Initials
         GE         Generational Qualifier
         OR         Organization
         UN         Organizational Unit
         DD or DDA  Domain-defined Attribute
 
         Note there is no label for ADMD. MCI Mail subscribers place
         that value in the EMS field.
