'Could happen' ??

We've done it for *years* with a python module as a regular service for a CMS.

Acts like a remote-controlled MUA, not the normal webmail client, as it uses
non-local smtp, pop, imap resources.

Lynx / lynx-ssl text-mode browser is another way - one you can try for yourself
really easily.

lynx http(s)://<your remote webmail account URI>

There are others.

As said, restricting *Exim* as to destinations is not hard.

Preventing general misbehaviour originating on your own server that might get
your IP blacklisted is a little more difficult. IPFW / IPF / iptables can help.

Preventing users from sending mail entirely, or otherwise restricting them to a
sub-set of destinations is a *lot* harder if you need to support a variety of
services on the same box.
