Re: RFC 952

Even if you change the fqdn on SMTP VS properties, the Message-ID in message
headers will not change. However, that shouldn't stop you from
sending/receiving mail.

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?-

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.- Hide quoted text -

I have an A record and Reverse record created for the mail server
"mail.domain.com. The mx record points to Postini for spam filtering
This is displayed correctly when telnet into the server. The problem
the unix server is having is the fact that mail server's local host
name Exchange_server and this is displayed within the message header
under the message id. Is there a way to remove this from the message
header. Below is the header information.
