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.
If I were to implement, I would use a milter instead of the builtin
sendmail feature. Most milters allow for whitelists and other niceties.
I actually find SpamAssassin by itself is quite adequate,
reducing spam to perhaps 5% of my email.
But if adding SpamHaus improves even this
I am more than willing to try it.
IMHO, it isn't worth the effort.
A while back I did some observations and found that greylisting was most
effective at cutting spam. By itself, it cut spam by 90% or more. So,
I only use greylisting + spamassassin.
