XADM: DL Delivery Restriction Fails Without Name Resolution

• Microsoft Exchange Server, version 4.0

SYMPTOMS

An originator of a message who is not a member of a distribution list (DL) can send e-mail to that DL even if the delivery restriction of the DL is set to accept messages only from its members. This problem occurs if the originator of the message does not resolve the DL to a Microsoft Exchange Server DN.

For example, joe@company.com can send e-mail to vp@corporation.com, where vp is a DL that only allows messages from its members.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server 4.0. This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
