Two copies of recent posts

[Paul Kosinski]

I've been getting two identical copies of recent posts to this list
(such as this item). This only started happening in the past 24 hours
or so. Is anyone else seeing this?

Upon examination of the headers of the two copies, it looks like ISC's
list-servers are doing the duplication. 

(The first part of the actual message follows the headers.)
