In my experience, it's more efficient to let the MTA handle the RBL
checks instead of Spamassassin. I can't remember what MTA the OP was
using, but it's trivial to set them up in Sendmail. On my employer's
boxes, I use the spamhaus.org lists, but on my personal box (where I can
be much more aggressive) I use a few of the rfc-ignorant.org lists and
ws.surbl.org. The spamhaus lists are checked first, and they're highly
effective.
Well of course this is true, but this opens the whole debate about
scoring RBL checks.
Doing it in the MTA gives you a true or false result.
Doing it in Spamassassin applies the principals of fuzzy logic by
assigning a score to the different black lists that should more
precisely reflect the accuracy of the list.
If your black lists never have any false positives, then you're good to
go. :)
