Set the qualify_domain to be the FQDN and rewrite it to your main
domain if the local part is not mailer-daemon (or other system local
parts).

I do this so general mail appears to come from domains but it makes it
easy to work out which machine some system mail came from.

# is this system mail ?
^(?i)(root|postmaster|exim|news|usenet|uucp|daemon|mailer-daemon)@ * Ff
# otherwise, rewrite the froms.
*@@ $1@${qualify_recipient} Ffr
