After playing with MASQUERADE_AS(), MASQUERADE_DOMAIN() | plus a few FEATURES(), I've managed to change the 'From:' address for | e-mails sent via the command line. Unfortunately, e-mails sent via the | cron-ed periodic scripts still don't get through, although if I run e.g. | 'periodic daily' from the command line, the mail does reach me. | | The only difference I can think of is that cron runs the scripts as | root. Could this cause the difference? Yes. root is specifically exempted from all the masquerading stuff. There's an EXPOSED_USER macro you can use in $(hostname).mc to control that.
