If you want to do this in your host, and do it properly, you have to
catch outgoing SMTP calls. There is nothing to require the user to send
through your MTA.

If you want to catch stuff going through your MTA (as a "better than
nothing" job), I would suggest writing a front end that does the
checking before exec-ing to the real MTA. However, that still doesn't
catch local users that use SMTP to get to your local MTA.

Yes, you'd have to do that.
