I'm guessing this means that a message has been received by the bounce
address for a list, but the bounce processing can't figure out what it is.
This would be for one of three reasons IMHO:
1. It's an actual bounce, but Mailman doesn't recognise the bounce format
and can't figure out which address(s) bounced. Mailman is regularly
updated with code to support more bounce formats, but there's probably
some out there that it still doesn't know.
2. It's spam sent directly to the bounce address.
3. It's a message from an actual list member that has been sent to the
bounce address, instead of the list itself or the owner address. Not sure
exactly why but I've seen this a number of times.
If your list is configured to have unrecognised bounce messages forwarded
to the list owner, you should be seeing copies of these messages. In my
opinion, this is a good option to have turned on unless you're seeing a
lot of these.
IMHO, the log fragment suggests that this option is actually on, so
presumably you (or the list owner if it's not you) have already seen
whatever this is.
If you really want to know what it is, you should be able to find the
relevant message ID in the mail server logs.
