email blocking - with user release

Hello All,

I would like to implement a blocking facility (similar to a spam filter
.... but not quite) for a corporate system.

The system will be located at the perimeter as a mail relay and will
check email for potential violations of the corporate AUP both inbound
and outbound.

Looking for expletives in text, lots of flesh tones in images,
potentially references to confidential material (which shouldn't
normally be emailed), large attachments etc. This will work on both
inbound and outbound traffic.

I would like the email to be quarantined and an alert sent to the
internal sender/recipient - at this time the alert can remind them of
the policy and they have the choice of releasing the email or deleting
it.

The company can choose to sample these alerts to check that people are
not breaching the policy and, becasue the sender/recipient has been
reminded of the policy they can't complain that they weren't aware of
the restrictions.

Does anyone know of a product which can sit at the perimeter and can be
configured for the following:
1. Searching for likely offensive text (preferably avoiding the obvious
false positives)
2. Searching for potentially offensive images (flesh tones etc)
3. [optional] Searching for document tags or other ways to identify
confidential info
4. quarantine of the above
5. alert to the sender or recipient for the above
6. Automated release by the sender or recipient

Mail Marshal is one of the leaders in this type of thing and I think it
can do 1,2 and 4 but I'm not sure about the others... Anyone know?

Cheers Brightwell

Pity the people from Scunthorpe.

I wish I had graduated "cum laude" rather than having a degree with
honours. Thinks ... perhaps I should start using it anyway.

It is rather sad that you are offended by flesh. It is even sadder that
you appear to be in a position to interfere with other people's
communications.

As it is bad etiquette to attach flesh to news postings, here's a link to
some pink flesh for you to practice on. But don't forget, not all flesh
is pink. http://photo.clifford.ac/me.links/tn/p4150714.jpg.index.html

Do you open all the company mail and insert little post-it notes? Go on,
you know you want to.

This picks up "fuck" but not "F U C K". Our own fuck censor at work
thought is was proper behaviour to instruct me to instruct my son as to
which words he should use in his emails. I think the real problem was not
the word fuck itself but that the automated rude word program that he had
installed kept making him read emails.
