Thanks to ALL. I made it using the header_checks method using
in main.cf: header_checks = regexp:/usr/local/etc/postfix/header_checks in header_checks: /^Received: from/ IGNORE Seems to work like a charm :-) The VPN way certainly was another valuable thing but of course it'd need lots of additional work on all the client computers and so it wasn't the quickiest way. However, the header_checks thing was a ver quick and easy solution.
