    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.
