Disabling some DNS tests

Hi, list, I'm currently running zen.spamhaus.org and cbl.abuseat.org
as RBLs over Postfix, how can I disable them in SA? (I mean, if I'm
already blocking connections which got listed in those RBLs, why let
SA check them? I suppose it should lower scan times...)


Thanks,



Luix

OK, Got it. Anyway, I tracked down the timing issues which drove me to
disable DNS tests to a problem with my nameservers. Now the scanning
times reported by Amavis are similar to the other servers I have. BTW,
thanks for the tip, I've disabled CBL testings in Postfix.

ZEN includes CBL, so you've got a duplicate test there.

CBL isn't tested in spamassassin (except via XBL).

You'll need something like this to stop the spamhaus tests:

score __RCVD_IN_ZEN 0.0
score RCVD_IN_SBL 0.0
score RCVD_IN_XBL 0.0
score RCVD_IN_PBL 0.0
score URIBL_SBL 0.0

Cheers,

Phil

SA checks all non internal/trusted received headers on the RBLs. Postfix 
only checks the connecting server. Therefore, SA will score messages where 
the connecting server may not be listed on an RBL.

I have RBL checks done in both places, myself.

You are most likely asking a caching nameserver, so there is no speed
difference. SA gets the cached response immediately.
