I agree with what you say, however I have a very different setup.   The
network users I am talking about are not part of my company or organisation;
I provide security for an Internet connection in a building occupied by many
different companies.

What happens to their systems when they're not in my building is not of
interest to me, and I have no responsibility to provide that sort of security.

If they bring an infected laptop into the building then it is their problem;
my firewall & mail server stops any infection spreading to other users in the
building.

What I am trying to achieve is a way to scan their incoming email for them
without having to redirect their MX records to my server, or modify their
mail client settings.   I can do all the proxying stuff with no trouble, but
I don't know if it's possible to get MailScanner to process the format of
files the proxy deals with.

Regards,

Antony.
