Hi everyone

All NANOG mailing lists were updated to use VERP (variable envelope  
return paths) at the beginning of the week. This will aid in bounce  
detection and help identify the subscriber. A more detailed  
description of VERP can be found here:

http://wiki.list.org/display/DOC/So+what+is+this+VERP+stuff

With this change some headers have changed. Depending on how you are  
performing your filtering this may or may not affect you. The header  
changes are:

Old Return-Path:  LISTNAME-bounces at nanog.org
New Return-Path:  LISTNAME-bounces+USERID=DOMAIN at nanog.org

Old Errors-To: :  LISTNAME-bounces at nanog.org
New Return-Path:  LISTNAME-bounces+USERID=DOMAIN at nanog.org

I hope that this change does not cause any serious issues for you. The  
mailing list admins are always reachable at admins at nanog.org if you  
have any technical questions.

Thanks!

Kris Foster
MLC Chair
