Been running it for years this way. This is for a small email hosting service. I use an implementation tied into spamassassin and exim that only greylists things that are suspected of being spam. Other stuff comes right in. I believe it also does not tie the greylist to the sending server, but rather according to sender name and message ID so that it does not matter if the sender switches servers. Which avoids the problems listed by Markus. I've had no known issues with my greylisting the way my system does it. The only issues have been mail suspected as being spam, ie, in spamassassin. But not with the greylisting aspects. I whitelist known senders like banks (specific from addresses) and things that are known to cause issues on our systems. Problems with greylisting are probably implementation specific. If you have issues with the implementation, see if you can tweek some parameters. btw, my greylisting service requires a min wait of 10 minutes. Don't remember any issues with it. If there have been, it was a long while ago. Chad _______________________________________________ MacOSX-admin mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-admin
