APPLIES TO


 * Microsoft Exchange Server 5.0 Standard Edition

This article was previously published under Q168356





SYMPTOMS
With the cc:Mail SMTP gateway installed on a cc:Mail postoffice, if Microsoft Exchange Server does not have the Internet Mail Service (IMS) installed, Microsoft Exchange users can send and receive SMTP mail, but all replies to incoming SMTP mail immediately result in non-delivery reports (NDRs).



CAUSE
The cc:Mail Connector maps all addresses of the form "user@domain.domain AT POname" to SMTP addresses. Therefore, the Microsoft Exchange user cannot reply to SMTP mail messages coming from the cc:Mail SMTP gateway.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem was corrected in the latest Microsoft Exchange Server 5.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
