[TowerTalk] multiple copies?

[jimlux]

Over the past couple days, I'm getting multiple copies of towertalk 
messages (e.g. the RG213 thread).  It's not the "reply all" thing..
Just wondering if it's my ISP/mail client, or something else.

The mail headers show that multiple copies are being sent from 
dayton.contesting.com[69.36.242.137] to more than one mail exchange at 
earthlink (e.g. mx-roseate.atl.sa.earthlink.net, 
mx-clapper.atl.sa.earthlink.net, mx-casero.atl.sa.earthlink.net) at 
different times (13:05:24,12:14:31,11:56:30,EDT respectively)... 
different ESMTP ids too..

The previous transfer from dayton.contesting.com localhost to 
dayton.contesting.com (69... IP address) was at 856 PDT (for all mails)
