Well, I do not use postfix, but qmail. I would however, create an autorepond telling them the new address and then fwd the old address to the new one.
But nothing to do with sieve, it’s at the SMTP level.

this means those emails are not actually delivered anymore.
Sure. That's how I interpreted your notification text "This message is sent automatically, and your message has NOT been read nor forwarded." If the message is not being read, why accept it in the first place?
For now, I would like them to *be* delivered, so we still have them in case something important comes in.
Speaking for myself: If I send email to a business partner, that email can be a) rejected, so I know I'll have to find another way to reach the intended recipient, or it can be b) accepted, in which case I expect it to be read/processed.
What you describe seems to be neither fish nor flesh to me. Using MTA rejects leaves no doubt that the *sender* has to become active. As I understand it, that is you goal, is it not?
