[Mailman-Users] Subscribers being deleted

[Rafael Salasnik]

On one of my lists 18 subscribers were deleted yesterday at the same 
time with no apparent reason. All the messages were in the format of:

"xxxxx at xxxxx.xxx has been removed from xxxxxx."

All addresses are aol, yahoo or hotmail/live. However other users 
with those accounts weren't removed For this group I have two lists. 
Some (but not all) belong to both lists but their subscriptions to 
the other list was not removed.

Any thoughts/suggestions?

Many thanks
