>> Does this mean I'm not doing any RBL checking at all now? Or will SA

so with 
and obviously set up rules here


my objective is i don't want mails scanned that are clearly spam say FAIL more than one GOOD rbl ie.

Spam Lists To Reach High Score = 2,, in other words i thought the defaults are way too conservative//

my question though is "does this in fact cause MailScanner to NOT let SA spend time analysing these Mails ?".


"would it be preferable to let postfix itself reject RBL'ed mails ?"

also for 
[gelgin at gfee MailScanner]$ grep skip_rbl_checks *
spam.assassin.prefs.conf:# skip_rbl_checks      1

is 1 the default or do i uncomment if i don't want checks ? unlike amavis i am not getting a good feel that RBL checks are really happening...

I've always done it the other way (MailScanner does the checks) but times change.  To reverse it, is it as simple as changing these from MailScanner.conf
    Spam Lists To Be Spam = 1
    Spam List = spamhaus-ZEN (or whatever one has in there)
and in the spam.assassin.prefs.conf setting skip_rbl_checks to 0 (zero)?

Will the "Spam Lists To Be Spam" setting matter if spamassassin is doing the checks instead of MailScanner?  If so, should that become zero as well?
