Hmmm. I just tried running some test probes against the MXes for <bellsouth.net>. From a "real" ISP feed, I connected no problem, and got immediate "OK" responses to MAIL FROM:<[EMAIL PROTECTED]>. I tried multiple probes against both listed MXes. However, from my home Comcast feed, I get a hangup before HELO, with the message that I'm blacklisted. It's a 550 code. I'm not sure if Exchange will consider that a permanent failure or not. If not, and you're blacklisted by them, that would explain the delay-then-failure you're seeing. Try turning on SMTP protocol logging to record a transcript of the SMTP session, and see if bellsouth is rejecting you. If you're not familiar with SMTP protocol logging, this article explains it pretty well: http://www.msexchange.org/tutorials/Exchange-Server-2003-Mailflow-Part-2.html You may want to check the IP address your mail server will be sending from to see if it is on any blacklists. I like the site http://www.mxtoolbox.com/blacklists.aspx for doing that. FWIW, I did run the address your list post came from (24.229.89.2) and the one returned for mail.{shirevalleydesign,moyersconstruction,sealcoatmydrive}.com (67.91.139.138), and both came out clean. Valid PTR records also exist for both. > The other 2 domains are moyersconstruction.com and sealcoatmydrive.com . DNS looks good to me. The delegation chain is valid, and I get consistent answers from all nameservers. I also ran ZoneCheck (http://www.zonecheck.fr) against them and it didn't find anything serious. It warned that postmaster@ the domains isn't working, which isn't good, but if BellSouth was rejecting on that they would presumably do so all the time. (Still, you should probably fix your postmaster mailbox.) > Turns out in doing some more looking, we can't access the > web sites internally either. Not being able to access the web sites probably isn't good, but may or may not be related to your mail problems. What happens when you try the web sites? Name resolution fails, connection times out, HTTP server error, something else...? -- Ben ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
