Yikes. That doesn't sound like a good time.
I would heavily suggest building a replacement SMTP server and migrating good users over instead of weeding out the bad ones. If it is that bad you have to assume the machine is compromised and maybe an IP change/swap is in order. Most RBL's block my IP and/or net block so a quick fix out of a black hole could be there.

I have slowly been killing off spammers mail accounts and removing the server from various blockilists. And the server has not been sending any spam for months now. I'm also able to send mail to almost everyone again, except to emails with the "gov.mb.ca" domain. I get the reply "refused by EDS blackhole list".
