2.1.4 failed to recognize a bounce

Using mailman-2.1.4-1 on Fedora Core 1, I received a
few bounces (from one user) that were shunted into
"qfiles/bad"
with a log message of:

Mar 31 01:20:19 2004 (1408) bounce message w/no
discernable addresses: <1080714020-1324@myrealbox.com>
Mar 31 01:20:19 2004 (1408) forwarding unrecognized,
message-id: <1080714020-1324@myrealbox.com>

See the attached "bad" message. I was certainly able
to discern from this message that the bouncing user is
"fancylad@myrealbox.com".
