DOCUMENT:Q164768 12-MAY-1999 [exchange] TITLE :XADM: DL Delivery Restriction Fails Without Name Resolution PRODUCT :Microsoft Exchange PROD/VER:4.0 OPER/SYS: KEYWORDS:kbusage ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - 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.
