Most of us run servers that pretty much do serious work ;-).. to each
his/her way. You can use RBLs at:
MTA: Very effective, but prone to false positives.. at times RBLs get
over enthusiastic causing collateral damage. Point in case SORBS
blocking hotmail and spamcop blocking yahoo/gmail
MailScanner: Haven't tried this one.
SpamAssassin: Best way to use RBLs as per my POV.. the bad part being
that mails originating from ROKSO (spamhaus) are accepted and then tagged.
I use it at:
1. The MTA level (spamhaus+spamcop+dsbl) and am quite aware of the FPs
but that is something we (me and my customers) are ready to live with.
2. A ton others are used at the SA level as Martin hinted.
3. We also run a few RBLs of our own to take care of my country specific
