For Unix shell users, this is easy: ssh to your server and run
mutt(1) or alpine(1) or the like. Yes, I know that's not relevant in
your case, but it's fun to mention. :)
If you're already using OpenVPN to secure their access to office
resources while on the road, consider that email is an office
resource too. Simply point the MUA to run throuugh the VPN, and
nothing useful can be gleamed from your Received: headers.

As Jeroen mentioned, header_checks(5) REPLACE or IGNORE action does
this, no patching nor recompile needed. Search the list archives,
there have been examples to do this very thing posted before. No,
your requirement is not so unusual nor special.
