I Wouldn't wait for another SMTP relay solution to come for solving
this. If people need to send mail to gmail there (and I believe this
ain't a big volume of mail), just setting up your connectors would solve
It's not a band-aid really ;) I doubt that gmail will remove your
"noisy" MX in a short period of time. It all depends on the urgency of
sending mail there.

Looks like my hunch was correct. When I telnetting into GMAIL's server
this time, I got 
421-4.7.0 Our system has detected an unusual amount of unsolicited
421-4.7.0 mail originating from your IP address. To protect our
421-4.7.0 users from spam, mail sent from your IP address has been
421-4.7.0 temporarily blocked. Please visit
421-4.7.0 to review
421 4.7.0 our Bulk Email Senders Guidelines. 15si118050wrl
This is really odd this is the first time I recevied a new message that
means something. Even now, if I were to telnet I don't get this message
but rather the 
421 4.7.0 Try again later, closing connection. 27si7409145wrl

Connection to host lost.
I must've hit them at some particular time. We are not sending any
SPAM, I think it's us sending them a bunch of NDRs and they're system is
thinking we're sending them bulk email. I did notice in my SMTP logs
that some domains that think NDR messages (messages with <> in the from
field) thinks its SPAM and will close the session. Hopefully once we get
this LDAP filtering in place we can circumvent this.

Thanks for the input. It's a pain in the A** to get anything changed in
here and will not get approved. They would want to find the solution
rather than a band aid. We are in the process of replacing our all our
gateway mx servers with updated SPAM solutions since ours is older than
dirt, so I'm hoping this issue will go away when this happens. Another
thing I noticed is that these two boxes take different routes out to
gmail when I tracert, I'm wondering if this has something to do with it
as well since logs also indicate transient network failure when talking
to gmail.
