I had this issue with one domain....algxmail.com. I never was able to resolve it. I, like you, don't believe that it is at my end. I suspected that it was the services that Allegiance used for hosting their email. They used the services of iPlanet.com. If I telneted into these servers...any of the 4 they used, I would have intermittent success with ehlo ahd helo messages getting responses.

Bednarz Sent: Wednesday, February 18, 2004 10:07 AM To: [EMAIL PROTECTED] Subject: [IMail Forum] Repost: One domain will not receive our mail Had internet connection issues... Not sure if this made it to the forum... Folks, I hope you can help. This ones got me twisted in knots. I have Win 2k3 Server IMAIL 8.05 hf1 DNS running on same box Small office, 130 accounts. I have had no problems with any other mail except for one domain. This one domain 99% bounces back after 20 tries. About 1% of the time gets through but usually after 16 to 18 tries. Of course they say it's us, and we say it's them. I have my server running behind a firewall NAT'd to a public address. They can send mail to us with no problems. We cannot send to them. >From my router outside my firewall, I can telnet into their smtp server and any others. From mail server, I cannot telnet into this particular smtp server. However I can telnet into any others (as many that allow that) By this I conclude that port is not blocked in my firewall. Plus, that would cause all mail to fail. No? I can traceroute to it. DNS appears to resolve it correctly. I am getting MX connect fail errors in my log for this address. Why only this address? If I were having problems with dns wouldn't all of my mail get returned? I checked the ip addresses in my registry and everything seems to be in order. Is it because I am running from behind the firewall rather than in the DMZ? Again, if that were the case why would only 1 stinking e-mail get hung up? Arrrrrgh. I am lost.
