Some do, some don't. It's usually more significant if the in-addr.arpa
registration varies significantly ... 'dsl-109234.something' is more
likely to be blocked than 'blackhairy.demon.co.uk'.

It sounds like you might be using the wrong DNSBLs. Today so far, my
mail servers have blocked 33301 connections, of which 25882 were blocked
by various DNSBLs; 19345 mails looked legitimate and 554 were scored as
spam by SpamAssassin (I don't use SpamAssassin to block for historical
and political reasons).

It's certainly good, but can be very CPU intensive if you get more than
a trickle a day.
