The main catch was to move qmail to listen only on localhost, since the external interface now has qpsmtpd instead.
So far, so good. No spam in the spambox this morning, at all. Most were caught by the Spamhaus DNS blocklist I already use, but the greylist whacked the remainder.
Would it not make sense to do it in the other order? Greylisting being much less CPU intensive than other spam blocking methods.
On a related note, personally I'm strongly opposed to block lists since:
a) they only work after spam has been sent
b) they catch far to many innocent victims
c) when other methods are applied properly, blocklists only improve results by a very small amount.
"b" being the main reason I don't like them.
