I'd guess its probably worth running some form of tcpdump like tool
and capturing a session.
I would expect you to see something like
(normal SMTP setup, MAIL FROM & RCPT TO lines)
DATA
(most of message body)
.
(rest of signature)
The dot is terminating the message body... and exchange ought to be
escaping it, but is lousing things up...
If my guess is on track, its probably mostly fixable by editing the
signatures you are gluing on to things.
That is seriously loused up though. There isn't a mail/anti-virus/
security appliance box in the way is there?
Another thing to do is try turning pipelining off in case its
something stacking multiple commands up early on, but the error
message doesn't look quite right for that. You can turn off pipelining
in ACLs by using the control = no_pipelining modifier, or overall by
using the pipelining_advertise_hosts host list (set it empty to
completely disable).
