Having mail communications problem with one domain. They have their
server configured to only receive mail from other servers meeting all
RFC standards. The message below is what the admin sees on his side
when we try to send mail.

2007-01-10 12:39:19 rejected HELO from mail.abcdomain.com [IP
address]: syntactically invalid argument(s):
exchange_server.mail.abcdomain.com

underscore is not a valid character for hostnames - therefore we are
rejecting the message. they must remove the underscore from their
hostname
before we can accept mail from them

This is an Exchange 2003 server and I'm not able too just rename the
server obviously. Could I resolve this issue by setting up a smart
host or front server to just send mail for the organization?- Hide

Yes I changed this setting. When you telent into the box it responds
with correct host name but I guess when it communicates with this UNIX
server it is showing the full name.- Hide quoted text -

Should I create another DNS entry or cname internallly for
mail.domain.com? I guess I'm not sure how this would change how the
mail server communicates with another server. When it announces itself
it is passing the host name. I figured this was part of the
intelligence of the information store.
