If a message is received from SMTP by means of an Exchange Server computer that is configured to perform MIME Internet X.400 Enhanced Relay (MIXER) address mapping, the address may be encapsulated in the X.400 address of the MIXER server, even if the recipient's SMTP address appears in the global address list. The recipient's address is displayed as an SMTP address instead of as the display name that is listed in the global address list entry (mailbox or custom recipient). If you double-click this name, the Address Type is displayed as X.400 and the full Address is the X.400 address of the MIXER server, with a Request for Comments (RFC) 822 domain-defined attribute (DDA) that contains the value of the SMTP Address. If there is more than one such recipient of this message, the reply to all option does not work.
For example, if an SMTP message is addressed to firstname.lastname@example.org, the message arrives over a MIXER server that has an X.400 address of "C=us; A= ; P=company; O=SMTP-GW," the recipient is known to MIXER and the global address list is replicated to this server; the message is not addressed to the SMTP address of the mailbox. The address is translated to the following:
C=us; A= ; P=company; O=SMTP-GW; DDA:RFCemail@example.com
This issue can occur because the message transfer agent (MTA) only resolves incoming addresses to route the message. In this case, the P1 (envelope) address is created from the global address list entry so the message can be delivered correctly, but the P2 (content) address, which is shown to users, is not resolved from the global address list.
