Hi Victor. Thanks for your reply. My problem is that I want to put all the emails in HOLD, apart the local one. As I said before, my installation is not exatly a standard one... I recognize local emails with: transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf where a database say me 'virtual' if the email is local, ':' otherwise.
So I don't know how to say to postfix which email will not be HOLD... I'm quite lost at the moment... can you put me in the right way? Thanks Michele
