I've had a reoccuring problem over the last several months of people
disappearing from my mailing list (ADND-L) without any notifications
being sent out and no records of this happening in the LISTSERV log
files.
 
Up until just a few days ago, this was a relatively minor problem,
affecting about 1% of the subscribers.  Recently, the frequency of
these disappearing subscriptions has increased dramatically.
 
I suspect that this increase was triggered by a rather large binary
file attachment which someone sent to the list, but I don't have any
concrete evidence of that fact.
 
Here's the settings I'm currently using on the list:
 
  Review= Private   Subscription= Open         Send= Private
  Notify= No        Reply-to= Sender,Respect   Files= No
  Daily-Threshold= 100
  Renewal= 6-Monthly,Delay(14)
  Validate= No      Auto-Delete= No
  Confidential= No  X-Tags= No      Stats= Normal,Owner
  Ack= Msg   Language= English
  Mail-Via= Distribute   Notebook= Yes,M/1A7,Weekly,Public
  Errors-To= [log in to unmask]
 
If anyone can help with this problem or even shed some light on
what's going on, I would appreciate it.  Thanks in advance.
