[void]

I have been running SpamAssassin for years, but the way it is integrated in to Zimbra is baffling me...

I have my /opt/zimbra/conf/spamassassin/local.cf set to:
required_score 5

and yet I get spam delivered to my inbox, with no subject line changed, that has
X-Spam-Status: No, score=0.9 tagged_above=-10 required=7


If the score is in excess of the required score, it should be tagged as spam, but it's not, Spamassassin thinks my requirement is 7.

I have changed the value to 5 in the following files:
/opt/zimbra/conf/spamassassin/10_default_prefs.cf
/opt/zimbra/conf/spamassassin/local.cf
/opt/zimbra/conf/salocal.cf.in
/opt/zimbra/conf/salocal.cf

How does one override the Zimbra default of 7?

Somebody has to know...
