"No false positives" seems a bit optimistic. One problem I've encountered in the past is big mail providers (like yahoo) who will send retries from _different_ servers, which sometimes don't even have a DNS entry (maybge it's just DNS propagation delay, I don't know). How do greylisting services determine that a message is being resent (and so should be accepted this time)? If it's by hostname or host address, this would sometimes fail with systems like the above. -Miles -- I'm beginning to think that life is just one long Yoko Ono album; no rhyme or reason, just a lot of incoherent shrieks and then it's over. --Ian Wolff -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
