I have recently taken over an email list run with mailman.
Some 50 odd mails/day with 175 users, about 40 of which are gmail users.
google has started complaining
SMTP error from remote mail server after RCPT TO:<XXXX@???>: host gsmtp147.google.com [209.85.147.27]: 450-4.2.1 The user you are trying to contact is receiving mail at a rate
450-4.2.1 that prevents additional messages from being delivered. Please
450-4.2.1 resend your message at a later time. If the user is able to
450-4.2.1 receive mail at that time, your message will be delivered.
450-4.2.1 For more information, please visit
450 4.2.1 http://mail.google.com/support/bin/answer.py?answer=6592
And then later:
2009-02-06 17:29:26 1LVUNx-0007Uw-N6 == YYYY@??? R=dnslookup T=remote_smtp defer (0): SMTP error from remote mail server after initial connection: host

The mail server hosts several domains (web and mail). It has one IP address where the reverse DNS has nothing to do with the domain
that is causing problems. I have been offered an extra IP address - I could make that have a reverse IP address that was in the domain.
However: I don't believe that there is a way of getting exim to bind to a particular address for a specific router or transport.
We are adding SPF records to the domain that include the mail server.
Any other suggestions ?
