...but you could set a global variable in filter_relay to reflect whether or not it only has a hostname component, then act on it where you can run action_change_header, change the SA score, etc.
Actually, no, you can't - filter_relay and filter_end can get run by different slaves, so variables defined in filter_relay aren't necessarily going to stick around. (See the Global Variable Lifetime section in the mimedefang-filter man page.)
...unless this has changed between 2.39 and 2.40 (I haven't upgraded yet).
