Why "localhost"? This would accept messages via SMTP addressed to
USER@localhost. I'm not sure, if this is intended.

Imagine your host ist named "dk". Where should user@dk go to? To Denmark
(.dk has an A record) or to your local host.
From my personal point of view, mail addressing should use FQDN always,
or no domain at all (destined for the *local* host, not *localhost*).
