[Mailman-Users] Some sort of spam filter, or a bounce I'm not seeing?

[Paul Tomblin]

Every time a message goes out to one person who is a member of my lists
(who has a uchicago.edu address), I see in the Postfix log what looks like
it should be a bounce:

Dec  9 15:00:45 xen1 postfix/smtpd[3315]: connect from relay01.uchicago.edu[128.135.12.136]
Dec  9 15:00:47 xen1 postfix/smtpd[3315]: DD9174F021A: client=relay01.uchicago.edu[128.135.12.136]
Dec  9 15:00:47 xen1 postfix/cleanup[3318]: DD9174F021A: message-id=<200612092004.AHW20671 at uchicago.edu>
Dec  9 15:00:48 xen1 postfix/qmgr[1276]: DD9174F021A: from=<>, size=5089, nrcpt=1 (queue active)
Dec  9 15:00:48 xen1 postfix/smtpd[3315]: disconnect from relay01.uchicago.edu[128.135.12.136]
Dec  9 15:00:48 xen1 postfix/local[3319]: DD9174F021A: to=<partyhats-bounces at xen1.xcski.com>, orig_to=<partyhats-bounces at list.xcski.com>, relay=local, delay=3, status=sent (delivered to command: /var/lib/mailman/mail/mailman bounces partyhats)
Dec  9 15:00:48 xen1 postfix/qmgr[1276]: DD9174F021A: removed

But then I don't see any mention of a bounce being recieved from her in
the mailman logs.  Is there some way to see if this is a bounce or if
there are bounces being recieved from her?  I've tried sending her direct
mail, and it doesn't bounce.  And she hasn't complained about missing any
messages from the mailing list.
