Using the Amavis "Soft" White List

Adding individual users or entire domains to the Amavis soft white list is possible. This differs from the hard white list. The difference between the two is that a score is still computed for items on the soft list, and then the soft list value is added to the score to produce, hopefully, a ham value.

The file is 20-debian_defaults under /etc/amavis/conf.d/

Find the section with the static hash table that occurs after the normally commented line of #read_hash(“/var/amavis/sender_scores_sitewide”).

Add entries as follows into the static hash table:
'user@domain.tld' => -3.0,
'wholedomain.tld' => -3.0,

Use negative values to soft white list, use positive values to soft black list.

Generally you will want to use this in response to sender mail being bounced back as UBE "Unsolicited Bulk Email", and should be used before progressing to using the hard white list array.
