Sorry about the previous my poor mind is dead this week.. Just finishing off
with Cronic Bronchitis attack..

Anyways: As for this, in a corporate sense, it should be in your policies,
like here I notified all our employees I may log their e-mail if I feel that it's
being abused, or used for suspicious behaviour.

Such as a recent case in which someone was due to be fired, because of his
attempting to sell the company without the Boards knowledge, hence I was
asked to monitor for this type of information, which can be criminal.

I don't like doing it, because it adds countless hours of scanning through e-
mail, but it was a necessary evil.

But this also leads to the fact that I have notified many customers that any
executable attachments may be checked over so as to determine if they are
infected or not, which I maybe actually look into 1 of 10 of these messages.
These are the ones that are infected but do not come up in virus scanning,
but surely was infected, after I did a strings on the file.

I also do not have much spam going through our server, though I do view it all
to determine if it's spam or not.. But if I didn't do it, we have on average 100
spam messages/day coming in, so it is alot of work, but again it's work..
