I spoke too soon. My last post does not work.
After digging through the amavisd code a bit, I've determined that the $sql_select_policy query will not work as an easy wholesale way to enable all domains to be scanned. The reason being is that this query is intended to return a list of policy values. The default query coded into amavisd actually looks like this:
$sql_select_policy =
'SELECT users.*, policy.*, users.id'.
' FROM users LEFT JOIN policy ON users.policy_id=policy.id'.
' WHERE users.email IN (%k) ORDER BY users.priority DESC';The simplest and easiest way to ensure that all email domains are scanned and tagged for spam is to use:
@local_domains_maps = ( ["."]);Sorry for the bad info in my original post.
