You need to configure as follows: 1) Configure Postfix to preserve the From: address in mail from this client. For control over Postfix header rewriting, see: http://www.postfix.org/postconf.5.html#local_header_rewrite_clients 2) Configure the client to send mail with the "right" From: address. The details for doing this are specific to the client. Wietse
