Hi,
I was just wondering, what's the "safest" dns blacklist? I know they're
never fool-proof, but what lists are people on the list using to deny
mail?
Best regards,

If there was one always-best answer to that question, there
would probably be far fewer blacklists... (100+??)
But if we 'could have only one' it would probaby be:
sbl-xbl.spamhaus.org
At the other end of the spectrum, one we consider pointless is:
dsn.rfc-ignorant.org
- because anything *meaningful* carried there can be detected
with Exim's own tests without need of a remote call, and will
catch entities not yet in the blacklist as well.
SpamAssassin will check a number of blacklists unless otherwise
configured. Both the list selection and what to do about a
'hit' change over time.
A look at the current SpamAssassin configuration and scoring
files. "20_dnsbl_tests.cf" in particular, may give you a
reasonable starting point - even if you do not otherwise use
SpamAssassin.
HTH,
Bill
