Do you know your
secondary MX doesn't resolve to anything?
This can cause additional
problems.. even though you have a cost of 20 if your emails aren't resolving to
your 10 cost DNS server, for whatever reason, it will try to your 20 DNS server
and then fail.
msmex02 doesn't respond
with my checker.

PTR record, yes. I
will explain. The one that works is from [EMAIL PROTECTED]
The one that does not
work is [EMAIL PROTECTED]
This does not work on
ONLY 1 specific external domain. [EMAIL PROTECTED]
The host record for
email.msmary.edu points to a front end server.
The MX record
email.msmary.edu points to the backend.
The host record for the
backend resolves to servername.mount.domain.msmary.edu. NOT email.msmary.edu
I hope that made
sense....

Do you
you a PTR record for mail.domain.com? (Why not just tell us what the real name
is?)

2000.
It only happens with one external domain. We can send to anybody else so
far.

Any ideas on this?
I have two exchange
servers. The users on one have the email address
of
[EMAIL PROTECTED] The other has an address of
[EMAIL PROTECTED]
When we send to a certain
organization, [EMAIL PROTECTED] goes through fine. If we send to the
same organization from [EMAIL PROTECTED] we get :
the following recipient(s)
could not be reached:
'Outside User' on 5/8/2002
11:20 AM
There was a SMTP communication problem with the recipient's email server.
Please contact your system administrator.
<My Server Name #5.5.0 smtp;550 rejected: cannot route to sender
<[EMAIL PROTECTED]>>
