The failure you're seeing when there are two addresses in the header is because your expression only matches when there is a single address. But header_checks is the wrong tool for this job; the To: header does not control where mail is delivered. A more robust solution is to limit where postfix can deliver mail. # main.cf default_transport = error:remote delivery disabled transport_maps = hash:/etc/postfix/transport # /etc/postfix/transport domain.com smtp: extern.domain.com smtp: http://www.postfix.org/transport.5.html -- Noel Jones
