The point was that the mail files are owned by the same uid that is
running imap process. It doesn't matter if the uid is in passwd-file or
not, it's just ls, ps and other userspace programs that map uids to
usernames using it.

So you would have to have same uid <-> username maps for Dovecot and
SMTP server, but they don't have to be anywhere else.
