That's why we all do our RBL checks in spamassassin.

Could you elaborate on this? I'm "new" to running a mail server (it's in test
phase atm) as my only experience is with sendmail many years ago. I take it SA
does RBL look-ups by default and there is no need to att RBL look-ups in
postfix main.cf file?

he should speek for himself and not for "us all"

a sane MTA setup is using something like Postscreen with scoring and *you don't want* to scan and tag 90% of all mails which are on 5 or even 10 RBLs, frankly you won't waste a smtpd process at all when postscreen can kill them

below the current month and scanning additional 200000 messages would waste ressources all day long
