Mitch I occasionally see this problem, but I do nothing about it. The ban is temporary (1200 seconds I think) and normal operations resume after that. My case is slightly different because I have a primary mail server at my ISP forwarding to my primary SIMS box. Using a secondary as a primary is a known spammer trick. They rightfully assume that all the anti-spam protection is concentrated on the primary. You could try adding a "fake" secondary which simply points to your primary machine and make the ISP box a tertiary. However, if they are really clever (this eliminates most) the spammer will use the lowest priority MX to send stuff to you. So why not try this: MX 10 mail.realsimsmachine.com MX 20 mail.fakesimsmachine.com MX 30 mail.myisp.net MX 40 mail.fake2simsmachine.com where the "*simsmachine.com" addresses all resolve to the same IP. I am not a DNS expert by any stretch of the imagination, so I am quite prepared to see this recommendation shot down in flames. -- Neil Neil Herber, RGD Corporate info at http://www.eton.ca/ Eton Systems, 15 Pinepoint Drive, Nepean, ON, Canada K2H 6B1 Tel: (613) 829-4668 ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
