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)?

Many mail clients, including webmail, offer the ability to warn the user about sending a message with an empty subject when they attempt to send it.  Would that help?

You could probably use the spam filter to check for an empty subject and score the rule so high that the message is rejected, but it would give an error that the spam score was too high, not that the subject was empty.

Another option would be to write a plugin for MDaemon that was executed during each inbound SMTP session.

The last idea would be to install SecurityGateway, I believe this can be done with SecurityGateway using its content filtering system.

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.
