Why not propely 'out-source' this to a Postfix map rather than modifying
main.cf.  Dynamic modification of main.cf is *seriously* brain-damaged
in my opinion.  Point a map at an LDAP DSA or an RDBMS database and have
the application update *that*.  Then Postfix checks the map.  Nobody
needs to get constantly hup'd and you aren't touching configuation files
that *should not be writable* anyway.
