I doubt it. The correct way to not route mail to local(8) is to take
the domain in question out of mydestination. With no local transport
available, but a domain is still listed in mydestination, Postfix
will probably just complain about "transport not available".

shown above is Mike's $myorigin, and it is listed in his

acceptance and enqueueing. The now-commented local checks the
alias_maps and does the delivery.

This won't work if local_transport points to a service which is

Probably a better idea, but that feature is not available in all
known cron implementations. Mike should check his own crontab(1)
