APPLIES TO

This article was previously published under Q140932

SYMPTOMS

If incoming SMTP messages include multiple Resent headers, replies from Microsoft Exchange Server recipients might go to an incorrect recipient.

CAUSE

The Microsoft Exchange Internet Mail Connector (IMC) will use the oldest information in the Resent headers to place in the From field.

MORE INFORMATION

Multiple "Resent" headers in an incoming SMTP message might look like:
