My statement is only true if the priorities are set correctly,
otherwise it would change this lookup behavior. As I said:

# The SQL select clause to fetch per-recipient policy settings
# The %k will be replaced by a comma-separated list of query addresses
# (e.g. full address, domain only, catchall). Use ORDER, if there

$sql_select_policy =
'SELECT *,users.id FROM users LEFT JOIN policy ON users.policy_id=policy.id'.
' WHERE users.email IN (%k) ORDER BY users.priority DESC';
So, what I get from this is, is in order to maintain the lookup order of:
[EMAIL PROTECTED]
@domain
@.
the priorities would have to reflect this order.
Again, I hope I am understanding this correctly, please correct me if
I am not.
