They can do what I did: Install Linux on a spare old "doorstop" computer
and use it as both a firewall and a mail gateway. You can run fetchmail
to gather mail from your external mailboxes, which pushes it through
sendmail to a local mailbox. Users inside the firewall connect to the
firewall to retrieve their mail.

I've seen several "Linux on a floppy" distributions kicking around. (For
example, a friend is using Freesco as a print server at the office, to
avoid buying a JetDirect.) Perhaps someone could adapt one to this kind
of application to make it easy for the average Outlook user to deploy.

Another approach is to implement the sanitizer in a POP3 or IMAP proxy
that runs locally. This is the approach that the Norton AV uses. The
local MUA connects to the proxy, and the proxy in turn connects to the
real mailbox.
