Setup blacklist and whitelist for SPAM filter:
Easy method
As root, edit the amavisd config at /opt/zimbra/conf/amavisd.conf.in, add 2 lines:
#vi /opt/zimbra/conf/amavisd.conf.in
read_hash(\%whitelist_sender, ‘/opt/zimbra/conf/whitelist’);
read_hash(\%blacklist_sender, ‘/opt/zimbra/conf/blacklist’);
Create the list files:
cat <<EOT > /opt/zimbra/conf/whitelist
sathish.com
EOT
cat <<EOT > /opt/zimbra/conf/blacklist
spammer@example.com
EOT
Then take effect by:
su – zimbra -c ‘zmamavisdctl restart’
Alternate method
Edit the amavisd config at /opt/zimbra/conf/amavisd.conf.in, at section:
$vi /opt/zimbra/conf/amavisd.conf.in

### Add custom black / white list here :

# blacklisting:

‘spammer.com’ => 10.0,
# whitelisting:
‘sathish.com’ => -100.0,

And run restart aamvisd to take effect:
$zmamavisdctl stop && zmamavisdctl start
Redefine your spam score according to your environment:
That required score is defined by a setting in your admin UI.
Go to Global Settings, the AS/AV tab, and you’ll see kill and tag percentages.
The “Required” score is 20 times the percentage in that tag field.
So for example, 20 * 35% (0.35) = 7. Change that to a lower number and you’ll have a lower required score–I have mine set at 24% which results in a required score of 4.8.
