This article was previously published under Q143375 SUMMARY
There are instances when an Exchange Mail client receives multiple copies
of the same message that is sent from the Internet via the Internet Mail
Connector (IMC) or by a Microsoft Mail 3.x client via the Microsoft Mail
Connector.
MORE INFORMATION
This behavior occurs if the Exchange recipient belongs to multiple Distribution
Lists (DL). For instance, if user1 belongs to Distribution List 1 (DL1) and
to Distribution List 2 (DL2) and an Internet or Microsoft Mail 3.x client
sends to both DLs, the Exchange client receives two copies of the
same message. If DL2 is a member of DL1, then the Exchange recipient
receives three messages.
This behavior is by design. It is an X.400 feature. Exchange Server tries to
eliminate duplicates, but for mail coming from external sources, the information that is required to accomplish the task is not available.
