Approved message is discarded

We are running Mailman v2.1.13 on Solaris 9 Sparc. We have a list with about 13,000 members that we currently have "emergency moderation" turned on because of previous problems with reply storms.
Today somebody sent a message to the list, which (of course) was held for moderation. The list owner approved it, but then it disappeared. Here is what was in the "vette" log:
Oct 04 10:35:12 2010 (21271) XXXXX_Cohorts post from michael.xxxx@xxxx.edu held, message-id=<2034674BF9D4714BAE35B22BF073EEF402E70996@MS-XXXX.xxxx.edu>: Post to moderated list Oct 04 10:38:26 2010 (5774) held message approved, message-id: <2034674BF9D4714BAE35B22BF073EEF402E70996@MS-XXXX.xxxx.edu> Oct 04 10:38:28 2010 (21271) Message discarded, msgid: 2034674BF9D4714BAE35B22BF073EEF402E70996@MS-XXXX.xxxx.edu
What caused the message to be discarded after it was approved?
Thanks,

The first and third line seem to match, but why is the size for the second line only a 5k instead of 20k? (if the number in () is actually the size)

Most likely, Content filtering -> filter_action is Discard, and there was nothing left of the message after content filtering. E.g. the message was text/html or maybe multipart/related and the list doesn't accept that content type.
