Whitelist senders in amavis

If you scan your outgoing mail, there may be times you don’t want check for spam on outgoing mail from a specific adress.

In that case, create a file listing the adresses you wish to whitelist, eg. /etc/amavisd.whitelist.

Then add the following rule to your amavisd.conf file.

read_hash(\%whitelist_sender, '/etc/amavisd.whitelist');
@whitelist_sender_maps = (\%whitelist_sender);

$interface_policy{'10026'} = 'VIRUSONLY';
$policy_bank{'VIRUSONLY'} = { # mail from the pickup daemon
 bypass_spam_checks_maps => ['@whitelist_sender_maps'], # don't spam-check this mail
 bypass_banned_checks_maps => ['@whitelist_sender_maps'], # don't banned-check this mail
 bypass_header_checks_maps => ['@whitelist_sender_maps'], # don't header-check this mail
};

The result being that you get virus checks but no spam checking. The headers are still added but look like:
