Many unexpected outbound e-mail messages appear in the SMTP queue in Small Business Server 2003 (835734)

SYMPTOMS

On your Microsoft Windows Small Business Server (SBS) 2003-based computer, many unexpected e-mail messages may appear in the Microsoft Exchange Server 2003 SMTP queues waiting to be sent to external recipients.

CAUSE

This problem occurs because of the way that the POP3 connector processes certain messages that it downloads from a POP3 server. The SBS 2003 POP3 connector may incorrectly re-send certain messages to recipients who are not part of your SBS 2003 e-mail domain. Because of this, Microsoft recommends that you install the update that is described in the "Resolution" section even if you do not experience this problem.

RESOLUTION

To resolve this problem, install the update that is available from the following Microsoft Download Center Web site.
