Hi, I was wondering if there were any plans to support greylisting. Greylisting is a wonderfull way of stopping spam and viri. In a nutshell greylisting gives an error to the sender of an email the first time the combination "from, to, IP" is encountered. A normal mailserver will retry a few minutes later, this second attempt is allowed and mail is accepted. After a few succesfull sessions the combination "from, to, IP" is whitelisted and consequent email will not be delayed. If a sender IP has shown that it did a few different good sessions this IP can be whitlisted also on the basis that this is probably a good mailserver, allowing all mail to be delivered from that IP. This works because most spam and virusses are sent by infected computers that do not behave like a 'normal' mailserver. Errors are ignored and there is no regard for the rfc on how to re-deliver temporarily failed mail. there is more to read on:
