However, in general it's better to use DNSBLs at the MTA level, which uses a lot less resources than implementing them in Spamassassin. So try and set them up in postfix first.
I conceptually agree.However, I prefer to do some RBL testing in SpamAssassin because I can easily check multiple RBLs and tag messages as spam, or reject, based on spam score. Conversely, most MTA's implement RBLs as a binary pass / fail situation. Thus SpamAssassin gives more flexibility and provides a configurable gray area that MTA's can't do themselves.
