OK, thanks. 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?
