So the incoming mail allready touches "your own" smtpd.
For outgoing mail, as i said, _smarthost_ and do the best you can to
block any mail that isn't going out through there. (eg via pf rules)
You will only catch the low hanging fruits as there are too many
possible ways to deceive by any determined person.
Blocking all webmail websites from work? :)
It only works if the people are not trying to get around the set
limitations. Even with deep packet inspection, you won't get that one
mail you setup all that hupla-di-do up for.
