XFOR: "Forward All Mail with Unresolved Recipients" Feature Does Not Work to All Hosts (278529)

The information in this article applies to:

Microsoft Exchange 2000 Server

This article was previously published under Q278529

SYMPTOMS

When you use the "Forward all mail with unresolved recipients to host" feature on an SMTP virtual server in Exchange 2000, messages may not be delivered correctly. The e-mail messages may sit in the queue to the host that is specified in Exchange System Manager, and messages may be sent over and over again, which causes time-outs.

CAUSE

This problem can occur if Exchange 2000 sends the message in STNEF and does not send "CRLF.CRLF" properly to end the SMTP conversation. The receiving host might continually log warnings that indicate that the session timed out.

RESOLUTION

To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
