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?
