A really strange problem.... I wonder if anyone has seen anything similar, or can offer any clues.

(Mailman 2.1.1)

I have over a hundred mailing lists.

List members can all post OK to the list The messages all appear in the archives for each list.

However.....

User A receives mail from some lists, but not from others User B ditto (but not the same lists necessarily).

Therefore there is nothing wrong with the user's address or ISP. The problem exists with hundreds of users, (but not all).

Some lists post messages out to all users Some lists post messages out to *some* users Some lists do not appear to post out any messages

There seems to be no reason, and no logic to the thing?

When a user doesn't receive list mail, unsubscribing, and then subscribing again doesn't make any difference.

Nothing has been changed in any configuration in MailMan, and no new lists have been added for a few months. Hard disks are nowhere near full. The problem began about a week ago.

Does anyone have any ideas??
