After having some success running a greylist on our second mail server (running debian/postfix/courier, used for virtual hosts that don't need all the advanced features of kerio) I wanted to implement it for our primary mail server running kerio and mac os x. Is there a way to do this or would it be advisable to just make it a feature suggestion?

We have a feature suggestion open, I'll add you to it.

Personally I never liked greylisting very much.

Thanks.

Yeah I didn't think about it too much either, until I ran it on my personal mail server (only a couple domains, maybe 50 - 100 emails/day) and after just a week I had 84 'valid' (ie, the server tried a second time to send it, some were still spam) out of 368 lines in the greylist file. And it's pretty much transparent since I set the retry limit to 5 mins (the 1 hour default is WAY too long IMO)

Our anit-spam gateway using grey listing. It is very effective. In combination with automatic whitelisting on outbound message addresses, false positives are < 0.01%
