I guess it's Postfix that adds the MAILER-DAEMON there. I get this:

May 15 20:22:39 hurina postfix/qmgr[31650]: 00615287D8C86: to=<@>,
relay=none, delay=0.24, delays=0.12/0.13/0/0, dsn=5.1.3, status=bounced
(bad address syntax)

Anyway, what it was supposed to do was just log it:

deliver(tss): May 15 20:24:41 Info: msgid=: Return-Path missing,
rejection reason: Quota exceeded
