Hi!

I have heard that entries that are older than 30 days and haven't sinned in that time are supposed to be automatically removed from blacklists.

Whilst this mechanism might be useful to me, I simply can't find any information backing this up... does anyone have any information?

It sounds like a "if you run a Blacklist, here's a list of rules to ensure you are fair" sort of convention, as I can't see how it could be enforceable. As far as I can tell, the best way to ensure a Blacklist contains accurate and fair entries is to see who uses it a la SpamAssassin.

There is no public information about that, not for SURBL since its not a per default pick. Any domain can get a specific listing criteria. So there is no such thing as you mention above. Not for SURBL at least.

Some entry's will never expire for example. This has nothing to to with beeing fair.

We have various ways of testing accuracy, SpamAssassin mass checks is one just of them.

Bye, Raymond.
