I also looked more closely at the smtp log you sent earlier. There are a
huge number of mailman generated notices that originate from
BounceRunner. All lists appear affected. I think these are unrecognized
bounce notifications. I have suggested before that there may be a large
amount of spam being sent to the LIST-bounces addresses, but there may
also be a mail loop of some kind. I suggest that you make sure that each
list's (including the 'mailman' list) owner attribute contains only
deliverable addresses and that none of the LIST-* addresses are among
them. Similarly, if there are any moderator addresses, they must be
deliverable and must not include any LIST-* addresses and shouldn't
duplicate any owner addresses for the same list.

Also try sending an email to the LIST-owner addresses to verify such
mail is received.
