Refusing messages with empty subject

Hello,
Several people in my company have the bad habit to send messages with empty subject.

Currently I'm handling this with a content rule that deletes the message and reports the sender about it, adding a note explaining the issue.

The downside of this method is that the sender is not warned immediately because MDaemon send the note/alert only once it has processed the local queue.

Does it exist an alternative way or setting to immediately reject messages evaluating the subject (empty or too short, let's say for example less than x char)?

Thanks for replying

The 1st option is available on all our clients, but users... simply ignore it totally. As many of us know, unfortunately the average user does not even read the warnings that Windows or programs give them.

Using the spam filter does not look as a good way, IMHO. Further, users wouldn't understand the error they're making.

Writing a plugin for MDaemon is not something for me/us (no devs / programmers).

And SecurityGateway... well, probably this could solve, but it's expensive solution, considered that we don't need/want all other features it offers.

I hoped that MDaemon would have some built-in setting related to this, an option related to the smtp parsing or message headers validation or something like that.
