In the upgrade to 6.0.7, the spam-assassin cf files were updated using the latest updated files provided by SpamAssassin. SpamAssassin changed the score of the RCVD_IN_PBL score from 0.905 to 3.335. Because of this when addresses are listed on the PBL lists they are scored with a higher negative score and the overall spam score is significantly higher. To return this score back to the 6.0.6 level, you will need to make the following changes:

Go to /opt/zimbra/conf/spamassassin/ and edit 50_score.cf file, locate and change

   score RCVD_IN_PBL 0 3.558 0 3.335 # n=0 n=2

to

   score RCVD_IN_PBL 0 0.509 0 0.905 # n=0 n=2

Edit STATISTICS-set1.txt file, locate and change

   39.995  58.9770   0.0262    1.000   0.94    3.56  RCVD_IN_PBL

to

   20.145  31.4714   0.1790    0.994   0.65    0.51  RCVD_IN_PBL

Edit STATISTICS-set3.txt file, locate and change

   39.995  58.9770   0.0262    1.000   0.94    3.33  RCVD_IN_PBL

to

   20.145  31.4714   0.1790    0.994   0.65    0.91  RCVD_IN_PBL

Restart the spam filter by running;

   zmantispamctl stop
   zmantispamctl start

Note: These files could be replaced the next time you upgrade your system.
