Ladies and gents, I'm about to start some gentle investigations into greylisting, but I need some advice on which policy server to use. It's off topic, so if you choose to reply privately I'll summarise.
I'm asking here because I think you're closer to the leading edge of spam control than the postfix-users list, and I'm sure that asking there won't receive an objective response. Actually asking here probably won't either but at least it will be varied :-) It will be working with Postfix on (sadly) multiple MX hosts for a couple of hundred thousand messages per day. I see two contenders: Policy daemon, http://policyd.sourceforge.net/download.html SQLgrey, http://sqlgrey.sourceforge.net/ I would love to hear from anyone who has experience with these packages, positive or negative. Thanks in advance! -- Andrew
