That's a Dovecot configuration problem.

You're mistaken, just the local part is not a valid address for anything
other than "postmaster". Dovecot is not configured correctly. It needs
to be able to accept mail for a suitable <user@domain> syntax, and
you can then configure Postfix to rewrite recipients to the desired
domain if necessary.
