 Are you using the same sendmail.cf file or configuration?

Subject: SMTP problem

Two weeks ago one of my servers was compromised and I had to rebuild it from
the ground up. I jumped a couple of versions, installing Fedora Core 5. I
dragged over my previous MailScanner directory and installed MailScanner
4.55-10.3.

I was having some odd problems with not several SMTP servers failing to
deliver mail, so after a couple of days of head scratching and with some
help here on the list I switched to Postfix. The text of the error messages
changed, but essentially the same servers would initiate an SMTP session and
then never close it.

Fearing that I may have caused some problems due to my unfamiliarity with
Postfix I switched back to Sendmail, but after many hours of fighting the
problem I still can't receive mail from several important mail servers. That
is, from several servers that are important to users on the system.

I'm pretty sure this isn't actually a MailScanner issue, but I figure that
there are quite a few experts here, so I'd appreciate it if anyone has any
idea of what I should be looking at. Below are four lines from maillog, each
pair of lines indicate a message that never arrived. Any suggestions would
be welcome.
