Presumably you are posting to this list because the systems running the
cron jobs have Postfix as their MTA.

What you mean by "announce themselves". Do you mean the envelope sender
address?

If they are running Postfix, you definitely can, or else why come here
to ask for help?
Why not set "$myorigin" to a real domain?

Why do you expect regular expressions to work in indexed tables? Pick
one or the other. Regular expression tables OR indexed tables with
fixed lookup keys. In this case, since the domain will match $myorigin,
fixed keys make more sense:
root r...@example.com

What is the setting of smtp_generic_maps reported by "postconf -n".

Probably using "hash:/etc/postfix/generic" in main.cf, when "regexp:"
is what you tested. That said, the regexp thing is unwise, there are
better ways of doing this.
