[Mailman-Users] Uncaught 550 reject bounce notification

I have a Mailman 2.1.9 Uncaught bounce notification:

     From: <>
     To: LISTNAME-bounces at example.com
     Subject: Returned mail: unreachable recipients:gingehen at wicc.weizmann.ac.il

     The original message was received at Thu Nov  8 14:58:21 2007

     Likely reason for failure: 550 5.1.1 <gingehen at wicc.weizmann.ac.il>... User unknown

Why was this not caught as a standard 550 rejection?  Is it because the
initial mail received a 250 return code

     to=<gingehen at wicc.weizmann.ac.il>,
     status=sent (250 Requested mail action okay, completed)

and then the mail was rejected?  But it is not the Mailman machine that
has the smart SMTP mailer; I send all Mailman mail via Postfix to
another machine for delivery.
