I have a spam tracking database at work which lists every possible reason a
message could be rejected and if it was. Each of the RBLs I have listed
will test each IP and if they are found they are logged. Order of this list
does not matter because of this. Here's what I have:
RBL: bl.spamcop.net Count: 12575
RBL: cbl.abuseat.org Count: 5349
RBL: dnsbl.njabl.org Count: 7646
RBL: dnsbl.sorbs.net Count: 7224
RBL: list.dsbl.org Count: 4924
RBL: relays.ordb.org Count: 262
RBL: sbl.spamhaus.org Count: 13717

I am actually surprised that spamhaus traps the most. I check through the
db occasionally to see things that weren't rejected (cbl.abuseat.org, ordb,
and sorbs are 2 that I don't use to block mail, they are statistical only)
From what I see, cbl and sorbs might block 2-3 messages a day if I were to
use them. Ordb might block one every week.
This information starts Nov 1 2003. I still have logs that date back to jun
2003. If anyone's interested, I'll compile the list.
