Probably not.

Sorry.

it looks as though everything survived but i had to redo the following and then it all tied in.

Spamassassin Config

Now we have PYZOR + RAZOR + SPF. But it would be advisable to enable it and give SPF a higher score. Those admins with wrong SPF entries should be punished since it's not mandatory and so, if you enable it, do it well. So open your spamassassin config at /opt/zimbra/conf/spamassassin/local.cf and add this rules at the end (customize it at your own):

ok_languages en es
ok_locales en es
trusted_networks 127. 10.70. 192.168.
use_bayes 1
skip_rbl_checks 0
use_razor2 1
#use_dcc 1 <<< WORK IN PROGRESS
use_pyzor 1
dns_available yes

## Optional Score Increases
## Choose your preferred values...
score DCC_CHECK 4.000
score SPF_FAIL 10.000
score SPF_HELO_FAIL 10.000
score RAZOR2_CHECK 2.500
score PYZOR_CHECK 2.500
score BAYES_99 4.300
score BAYES_90 3.500
score BAYES_80 3.000
bayes_ignore_header Received: from mail3.example.com
bayes_ignore_header Received: from localhost
bayes_ignore_header Received: from mail1.example.com
bayes_ignore_header Received: from mail2.example.com

as well as this

Change /opt/zimbra/conf/spamassassin/v310.pre to enable the DCC plugin:


loadplugin Mail::SpamAssassin::Plugin:CC

once i restarted amavis everything seemed to be fine. i assume it's working.

my RBLs were untouched as well.
