Phabricator sends mail to itself to the no-reply address, with valid users in CC.
Those mails are discard by Postfix.

GPT-5.6-Sol idea:

Confirmed: Phabricator deliberately uses its default no-reply address as a recipient on some notifications. As Postfix currently rejects that recipient before DATA, we’ll declare notifications-noreply@devcentral.nasqueron.org as a valid blackhole mailbox and silently discard mail delivered to it.
