I'm not sure why you're posting this to exim-users since the mailq output
you quote above is not from Exim. It looks like a recent version of Sendmail
given the queue ids above.
In any case, it's likely that the problem is mail1.aaahawk.com's firewall
which appears to be a Cisco Pix with their 'MailGuard' enabled. This causes
problems with various mail servers that result in problems like the above
(SMTP sessions failing to complete, connection resets, etc). I suspect if
they turn that off ('no fixup protocol smtp') the problems will go away.
Mailguard offers nothing but a false sense of security at the expense of
ESMTP and reliable mail delivery.
