Is it possible to configure Postfix to collect mail from non-existent mailboxes?

Question

linux

I used iRedMail to run the mail server. Created a virtual domain, several boxes are all ok.
Now there was a task to collect mail for nonexistent mailboxes of the domain.
That is, put letters sent to non-existent users of the mail domain in a separate box.
Emails for existing users are delivered only to them.
Is this possible with little blood? Found tips for collecting all mail and all mail, including non-existent mailboxes.
