I got 11 messages like this today. All timestamped 7:00 AM:

  Subject: ScreenplayLab unsubscribe notification
  From: mailman-bounces at movieeditor.com
  Date: 7:00 AM
  To: ScreenplayLab-owner at movieeditor.com

  <email addrees> has been removed from ScreenplayLab.

where "email address" is a subscriber's address, mostly from yahoo, 
hotmail, or aol.

Thanks, will look for those the next time I send out a post. There's no 
diagnostic # in the unsubscribe messages. I don't have any earlier 
messages because I unknowingly had it pointed to an invalid email address.

Both the bins and their contents are processed in hash order?
Why wouldn't the bins be processed sequentially?

Thank you,
