Well I am certainly open to suggestions.
The spam is causing war time conditions here. We haven't been able to concentrate on filtering the spam because there is so much coming in we can't even deal with the number of connections hitting on the server.
My free project at IMGate.MEIway.com has saved the bacon for many ISP's. It's not only for Imail or FreeBSD, it just started out that way. It runs in front of Imail, sendmail, Lotus, Exchnage, etc because it's a pure SMTP relay.
Putting an mailbox server as MX is simply asking for the kind DoS you are experiencing.
