http://blogs.technet.com/dlemson/archive/2004/07/02/172281.aspxIn a recent comment , Mark Hicks asks: Is there a way to accept a message for an invlaid recipient and then delete it without generating an NDR to the (usually fake) sender? I still want to generate an NDR for my internal users when mail cannot be delivereden-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.technet.com/dlemson/archive/2004/07/02/172281.aspx#172535Sat, 03 Jul 2004 19:46:00 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:172535ChrisThe only legitimate circumstance i can see for not wanting to generate an NDR is in the instance where the origniator of the original e-mail can be determined with a high level of certainty to be forged (e.g. when the message is generated by worm known to forge that information). In that instance the MTA is basically 'dumb' and the determination is properly handled by a content filter, such as an AV product. Sybari and other have intelligent worm handling and with Exchange Edge services I can imagine several other ways to educate the MTA to make more intelligent choices about what to do with a message (and any resulting NDR). http://blogs.technet.com/dlemson/archive/2004/07/02/172281.aspx#175248Wed, 07 Jul 2004 16:05:00 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:175248TrackBackExchange-faq.dk - Din portal til Microsoft Exchange Server informationhttp://blogs.technet.com/dlemson/archive/2004/07/02/172281.aspx#363697Mon, 31 Jan 2005 14:48:00 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:363697Welcome to Flaphead.com @ Homehttp://blogs.technet.com/dlemson/archive/2004/07/02/172281.aspx#2613708Thu, 06 Dec 2007 00:36:31 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:2613708The RFC 2821 "Covenant"<p>PingBack from <a rel="nofollow" target="_new" href="http://maxfeed.ath.cx/item_580777.html">http://maxfeed.ath.cx/item_580777.html</a></p>
