I've recently implemented Grey listing and I'm totally impressed. I'm
dropping 300+ messages a day that don't try back after being told to try
back in 30 seconds. The very few that do get through Spamassassin swats.
I have my inbox back!

Grey listing is cool, and it is the one tool I have yet to use against
spammers... The fly-by night guys drop the spam to you via a broken

not yet been added to anyones Block-list. Gray listing will definitely
work very well against a misconfigured mail server.
I would love to front-end my mail services with an OpenBSD box... Thanks
for the HeadsUp Magnus! Maybe I'll give that a try first, before putting
in a C/R system. I'm not too hopeful though as Spammers do seem to adapt
rapidly these days. We really need to press for smtp-auth to become the
standard of the 21st century.

It's unfortunate that "spamd" also refers to a deamonized version of
spamassassin. Is anybody using this OpenBSD version on Linux?
Also, how is this harder for spammers to work around than anything
else? I was under the impression that many (if not most) pump-and-dump
spam programs ignored RFCs to the point that they didn't wait for any
replies whatsoever, so this OpenBSD system would have no effect on
those programs. Am I wrong?
Thanks,

Informative and fairly entertaining. Take that you spammers! :-)
