[Mailman-Users] List Probe Problems

[mailbag]

Hi,

For some reason, users who have bounced mails back, end up getting the
probe email later - and it includes attachments with all the other
bounced probe emails, which includes other user's passwords to the list.

I haven't been able to track down the cause, nor have I found references
to anyone else having this problem.  Any suggestions would be
appreciated.
