Spam Filters just stopped working.

[SurrealSystems]

I had spam filters working great, and all of a sudden they have just stopped.

Doing zmprov gacf | grep zimbraMtaRestriction

Shows

zimbraMtaRestriction: reject_rbl_client zen.spamhaus.org


Shouldn't there be more than that?

How can I make the spam filters more effective?

Hey Surreal glad to see ya again,
What version are you on?
(There was in infamous bug where modifying the global settings in the admin console emptied those, plus we've gotten better about keeping enabled RBL's on upgrades.)
