Had an issue once with an W2K box running Exchange 2000. May was received alright but wasn't delivered. I don't know the error the sender got back.. I didn't install that box in the first place but was called in because the other consultant didn't solve it within 60 hours..
I added the IP (internal) of the Exchange server to the local DNS and delivery started again.
Have a look at it.. perhaps it solves your problem too.

Hello,
Yesterday I put our new exchange2000 server in, and everything is working fine, apart from incoming SMTP mail - it gets bounced with something along these lines to the sender:
>Reporting-MTA: dns;mail.<mydomain>.com >Recieved-From-MTA: dns;smtp.<ispdomain>.com >Arrival-date: Sun, 9 Mar 19:39:12 +0000 > >Final-Recipient: rfc822;me@<mydomain>.com >Action: Failed >Status: 4.4.6
I've checked this kb article http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B256321
And it says:
4.X.X Persistent Transient Failure X.4.6 Routing loop detected
Note these addresses have been created on each mail box, so they do exists here, and I've added the external domain name as the default email domain in the recipient policy.
I can send mail to external addresses fine, so I'm fairly sure this is my screw up.
Some info on my setup:
-The exchange server is behind a firewall, and you can telnet to the mail server fine from outside. -The <mydomain>.com domain is hosted by our ISP, and the internal AD domain is called domain.local (the AD dns server has no idea about our ISP's DNS , all external name resolving is handled by the firewall/router). -our incoming SMTP mail is forwarded to us by our ISP, and I can telnet into my mail server from the internet with no problems. -I've set the FQDN in SMTP virtual server->properties ->delivery-> advanced to the same as the MX record our ISP's DNS server. Doing this was probably completely wrong, but it didn't work before I did this either...
It appears that the exchange server is recieving mail (which suggests it's not a DNS issue), it's just not delivering it to the correct mail boxes and bouncing it... I can see the SMTP attempts and rejections on the firewall monitor...
I'm in a serious bind here, I've spent my whole weekend trying to fix this :/ If anyone could help, I would be eternally grateful, and shower you with gifts...
Yours hopefully, stephen gaffney
