I know I just said this in another thread, but it bears repeating. If you are using greylisting of any sort, you should read the information at http://greylisting.org/ and check back periodically for updates.
Just about all the additional ideas about greylisting I've seen in the "seal of doom" thread have been covered in detail, including managing database sizes, whitelists, and sharing lists of known-good smtp servers. I've been running greylisting on my personal mail server for over a year now, with a 5 minute delay timeout. Works great. I use SpamAssassin via .procmailrc after that, and it knocks out the vast majority of the spam that gets through. I update it using rules_du_jour nightly. --[Lance] -- Celebrate The Circle http://www.celebratethecircle.org/ Carolina Spirit Quest http://www.carolinaspiritquest.org/ My LiveJournal http://www.livejournal.com/users/labrown/ GPG Fingerprint: 409B A409 A38D 92BF 15D9 6EEE 9A82 F2AC 69AC 07B9 CACert.org Assurer -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/
