Hi, I forgot to say that I am runnning OpenBSD 4.2 and spamd in greylisting mode and all default parameters (-G).
My understanding is that if an IP address, after 4 hours of the initial greylist entry, has not been whitelisted yet, then it was a spammer who gave up because of the greylisting process. But I am not quite sure if there other (signifcant) situations which may occur in a similar way that I should not account for. Thanks for any comments. Regards, Jose. -- Want an e-mail address like mine? Get a free e-mail account today at www.mail.com!
