Filter to - Forward, discard and send an error message

[PeoplePeople]

Hello!
I want to disable an account without actually deleting it and I want a specific behavior when someone sends an e-mail to that account:

Example:
When someone sends a message to [email protected] I would like to:

1. That message to be forwarded to [email protected]
2. That message to be discarded from [email protected]
3. A custom error message to be sent to the sender.

I manage to create 1&2 without 3 or 2&3 without 1.

Any advice how could I do this 1,2 and 3? Is this possible?

Hey there! I answered this one on Reddit, but I'll leave this marked as new to see if people have other ideas.

Yes. cPRex offered me a solution, but it's not working.
His solution: Exim filters


Maybe someone had another idea.
