in smtpserver, we store dmarc evaluations (under the right conditions). in dmarcdb, we periodically (hourly) send dmarc reports if there are evaluations. for failed deliveries, we deliver the dsn quietly to a submailbox of the postmaster mailbox. this is on by default, but can be disabled in mox.conf.
