You can restrict "mail" command submission (with the main.cf
authorized_submit_users parameter) to root etc. accounts, and force
ordinary users to use SMTP. Many command-line tools including MUTT
and PINE have a submit-via-smtp option.
There is a nice plugin at policyd.org that implements various SMTP
limits for Postfix.

That is best done inside the extension: in a policy daemon or
content filter.
