To a certain extent that is already being done but these are small
emails and they typically go out on a Saturday and even rate limiting
still sees a hell of a lot of mail going out.

It just makes sense for me to RBL check the sending servers because that
is where the problem is and indeed we are finding these sending servers
listed on RBL servers - ours does not seem to get blacklisted.

One of our ISP's is able to notify us when there is an issue from one of
our client ISP's and we jump on and clean up the infection. I'd just
like to do the same at my server.
