XCON: X.400 Address Is Given SMTP Address Type If Received Over Connector with MIME Internet X.400 Enhanced Relay Heuristic Set

Article ID: 262691

Article Last Modified on 10/26/2006



APPLIES TO

  • Microsoft Exchange Server 5.5 Service Pack 3



This article was previously published under Q262691


SYMPTOMS

If you receive a message from a remote X.400 system that is also addressed to another remote X.400 user, the address of the remote X.400 user may be correctly displayed but the address type may be displayed as Simple Mail Transfer Protocol (SMTP). You cannot reply to this other recipient.

CAUSE

This problem can occur if the message entered the organization over an X.400 Connector that has the HEUR_MIXER_TO_SMTP heuristic (0x20000000) set. A logic error in the code causes this X.400 address, which is not resolved against the global address list, to be given the SMTP address type.
