Hi,
I have SBS 2008 with exchange 2007 on it.
Everything is working perfectly except that when I'm sending mail to one of my clients (only one domain example.com)
My mail stuck in queu.

I've used network monitor to trubleshoot the problem and I can see something like this (code belowe)

Why my server terminates connection?
Why it's not trying to use HELO command?

Who can I make it to work?

Best Regards
FooKy

Client -> Me 	SMTP:Rsp 220  mx2.example.com ESMTP
Me -> Client 	SMTP:Cmd EHLO remote.mydoamin.com
Client -> Me 	SMTP:Rsp 402  4.5.2 Error: Command uknown
Me -> Client 	SMTP:Cmd QUIT, Terminates the mail session
Client -> Me 	SMTP:Rsp 221  2.0.0 Bye

OK, I found the solution.

It was my firewall.
It was changing EHLO command to XXXX

NO FIXUP PROTOCOL SMTP 25

And everything is working.

Ah - the usual Cisco SMTP Fixup problem.  Could have told you that if you had posted your environment details, but as long as you are working, then that is what counts.
