I've just setup Zimbra 8 (coming from 5). My 5 configuration was kind of a mess, as I ended up editing config files at times. I'm trying to configure this installation the "right way."
[zimbra@mail ~]$ zmprov gacf | grep zimbraMtaRestriction
Shouldn't one of these stop these type of connections...?

Or is the idea we still let the mail come through and add spamassassin points?
