   Event ID: 11201
   Source: MSExchange NNTP

CAUSE

A bi-directional pull feed connection has been set up from an upstream server. When news is pulled down via that server and the articles include the header, NNTP-Posting-Host, the downstream server tries to post these articles back to the upstream server. The articles have the NNTP-Posting- Host header so the upstream server rejects them. The header is tagged onto the articles coming in to the upstream server when it receives those articles from its source, for example, a client.

STATUS

This behavior is by design.
