I have not found blacklisting to be particularly useful myself. I
wouldn't suggest it. I've not researched all of the blacklisting
services...but some of them are what I would call "hostile" or
"xenophobic". Besides, there is a certain level of overhead associated
with using these.
Absolutely. If using an RBL it is important to understand that you pass
out the control over who's mail can come through to a third party where
you have no influence about. Spamhaus is certainly one of the good ones,
but they decide whom to list and you adopt that policy.
+1 for using a milter rather than using the dnsbl feature.
