[wplug-bsd] OpenBSD spamd question

[Benjamin Slavin]

Has anyone here had an experience with OpenBSD's spamd? I'm considering 
implementing it, but I'm curious how well it works and how easy it is to 
use.

Note: This is different from the spamd listed in FreeBSD 5.2's man 
pages, which is simply a SpamAssassin daemon.

For those unfamiliar with spamd, here's a quick bit from the man page:
8<---------- SNIP ----------
spamd is a fake sendmail(8)-like daemon which rejects false mail.  If the
pf(4) packet filter is configured to redirect port 25 (SMTP) to this dae-
mon, it will attempt to waste the time and resources of the spam sender

spamd is designed to be very efficient so that it does not slow down the
receiving machine.  Spam is never accepted, but always rejected with ei-
ther a 450 or 550 error message.  The normal way that spam has been dealt
with in the past is to either accept and drop, or outright block.  When
configured to use 450 responses, spamd takes neither of these actions: it
rejects the mail back to the senders' queue.
