Is it possible to set up a callback on a specific action in postfix?

Question

Email

Hello. Tell me - is it possible to set up a callback for a specific action in postfix?
Now I'm looking at the postfix log, there are similar entries:
said: 550 Message was not accepted -- invalid mailbox. Local mailbox [email protected] is unavailable: user not found (in reply to end of DATA command))
Is it possible to configure postfix so that a certain script is called when such a response is received? To remove from the database of users, email, which does not exist.
