Sendmail Undeliverable Redirection?

Dizzle asked:

Good afternoon;

I don’t know much about sendmail, so this may be fairly easy for those of you more experienced with it. We have an account, “[email protected]”, sending reports to various groups. From time to time an undeliverable message will be sent back to “[email protected]”. We’d like for those undeliverable messages to be rerouted, or bounced, from “[email protected]” to a group of our choosing. To carve out a scenario for clarity:

• [email protected] sends a report to [email protected] and [email protected]
• [email protected] has someone who’s mail account no longer exists, triggering an undeliverable message being sent back to [email protected]
• Rather than having the undeliverable message sit in [email protected]’s Inbox, we’d like for it to be automatically rerouted/bounced to an admin group, [email protected]

So I guess a “rule” of sorts. I’ve come across this solution: Sendmail : ignore local delivery
But I don’t know enough about sendmail to know if this is what will fit this situation. Any help is greatly appreciated.
