We are using the following RBL's on our MTA right now:
Spamhaus (sbl-xbl) DSBL NJABL (dynablock)
Of the ones above, I only use spamhaus, combined with opm.blitzed.org & relays.visi.com
i use the same ones as Patrick, but i also use the cbl (a component of the spamhaus xbl, perhaps the only one at the present time, but that could change.) one thing i do is use opm.blitzed.org and cbl.abuseat.org at connect time. hosts on these lists are pretty much guaranteed to be open proxies or compromised hosts, so listening to them at all is a waste of time. no need to wait until after RCPT TO: to 5xx, i just drop the connection.
Also, I like sender verification, but that's me.
i used it for some time, and reluctantly shut it down. blocked a lot of email abuse, but too many false positives for my taste. richard -- Richard Welty rwelty () averillpark net Averill Park Networking 518-573-7592 Java, PHP, PostgreSQL, Unix, Linux, IP Network Engineering, Security
