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, “”, sending reports to various groups. From time to time an undeliverable message will be sent back to “”. We’d like for those undeliverable messages to be rerouted, or bounced, from “” to a group of our choosing. To carve out a scenario for clarity:

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

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.

My answer:

Use an actual mailing list for this, instead of the ad-hoc stuff you’re doing now. The mailing list software will then catch bounces and deal with them for you.
