My sendmail can send to everyone except 1 external domain...

I've done a LOT of work on my mail server to ensure that the 6 domain names hosted on this server can receive and send correctly. It is almost perfect. I can't get confirmation that my mail server is modifying the sender address via the genericstable yet... but so far everything is ok.

Except for intermedia.net. We use AdvancePro from AdvanceWare.net. I am trying to email their support, but they use intermedia.net to host their email. EVERY address i try to email@advanceware.net bounces back with the following: "relay=smtp.intermedia.net. [207.5.72.110], dsn=4.0.0, stat=Deferred: 421 4.7.0 exmf-1.intermedia.net Error: too many errors"

To my dismay, though I can turn LOG_LEVEL to 15 and see the individual commands that occur when an INCOMING connection is made, I can't get the OUTGOING connections to be shown to help me figure out what needs to be fixed!? All I get is: "SMTP outgoing connect on mail.masondrywall.com" and then the error mentioned above. I even tried LOG_LEVEL as 98. Nope. Even after full make and restart of sendmail I get lots of useless information but still no outgoing smtp commands/responses.

How can I debug this? What LOG_LEVEL should I use? No, I do not have any other problems sending to any other domains. And yes, it is plugged in. =)

I'm in the process of filtering the tcpdump and getting wireshark to open it.

My genericstable shouldn't have anything to do with intermedias mail server... right? I mean I'm not trying to send AS advanceware, I'm trying to send TO advanceware. Like I said before, my domains, my server, my users, nobody has ever had trouble before with email. It's only with SENDING to advanceware.net. (Oh yeah, receiving works just fine... I get everything advanceware sends me!)

I'll post my tcpdump results in a minute.

Ok, I finally got wireshark downloaded and installed.

Attached is my analyzed tcpdump. I see a HELO command not recognized... is that the problem (see line number 31)?

Wow... I just tried it manually. Help me figure out this...


If I do the HELO mail.mydomain1.com command... thinngs work just fine. But if I do EHLO mail.mydomain1.com (like my mail server does) it exits with deferred Error: too many errors. (Error, command not recognized)

So Hmmmm...... how can I ensure that my mail server tries HELO instead of EHLO? Should I make it ALWAYS do the HELO version? Or should I force HELO to this domain only?
Reading further I discover that EHLO is supposed to be used only when the server reports to be an ESMTP service (have ESMTP in the greeting line)

So in this case, the server reports: 220 exmf011-11.intermedia.net Microsoft ESMTP MAIL Service Version: 2.0


So why is it not recognizing EHLO?
