May,
Regarding this problem, do you, by any chance, have a Firebox Firewall? If
you do, Microsoft has an article about how the Firebox strips ESMTP
information in such a way as to make messages undeliverable. The solution is
to NOT use an SMTP Proxy but instead to use an SMTP Filter. What we did was
use an SMTP Proxy for inbound email and an SMTP Filter for outbound. These
settings are all configured within the firewall itself and you'll need to
contact the Firebox people for more detailed info on EXACTLY how to do it
step-by-step if you're not sure.
Good Luck
