OT: Pop3 Proxy

Yesterday I had a mass mailing virus get into the office.  At first I
was quite surprised that it made it past Mailscanner.  I haven't seen a
single virus in months (since I first installed Mailscanner).  After
some investigation I found that it originated from someone in the office
who was checking an external pop3 account.

My first reaction was to block all external pop3 connections at the
firewall.  My CT0 wasn't happy with that solution.  He thought it would
cause to much of a disruption.  I had considered installing a pop3 proxy
on each client machine (similar to Spam Assassign pro).  However that
involves too much client configuration.  So my next idea was to setup a
transparent pop3 proxy which would run some type of virus protection,
and possibly a spam filter.

Does anyone know of such an application?  Or has anyone used such an
application either currently or in the past?  Reviews?

Julian have you ever thought of creating such an application?  It would
be great to have the same protection from external pop3 servers as I do
on my own mail server.
