Create a custom transport in master.cf. Start with a copy of the default "smtp" transport. Use -o smtp_helo_name=host.example.com to override the HELO name, use -o smtp_header_checks=regexp:/path/to/file to strip existing Received: headers. Note: stripping Received: headers is generally considered bad practice since it removes important tracking and debug information. Some anti-spam engines will penalize mail with no Received: headers. And of course you can't suppress the Received: headers added by the server you're delivering mail to. Your master.cf entry will look something like this: mangle unix - - n - - smtp -o smtp_helo_name=host.example.com -o smtp_header_checks=regexp:/etc/postfix/smtp_header_checks Use a transport_maps entry to direct the single user to the custom transport. -- Noel Jones
