Odd Issue

[awsiemieniec]

I have a server (SBS 2003 with Exchange 2003 SP2) and when users on the domain send mail to any craigslist ad ([email protected]) it will NDR with 4.4.7.

If I putty telnet sale.craigslist.org 25 I get "host does not exist" (and I get the same from my local PC - not on that LAN).

Any ideas? The server is using OpenDNS. Server public IP isn't RBL'd.

No one has had an issue like this before? It's great being unique.
