Changing 'From:' address of periodic scripts

I set up a remote box to e-mail 'periodic' output to me directly.  It has now
stopped working, and I suspect it's because the 'From:' addresses of the status
e-mails is of the form 'root at mybox.local' and the ISP has upped its anti-spam

I see /usr/sbin/periodic itself uses the 'mail' command to send the mails, but I
couldn't see a command line option to specify a 'From:'.  I guess 'mail' uses
'sendmail' to send e-mail; is there a simple way of forcing a 'From:' address
via 'sendmail' config?
