Here's a partial mail header, with valid From and To lines:

Date: Sat, 30 Oct 2004 03:49:12 +0900
From: Ashlyn J. Nadeau <[log in to unmask]>
To: [log in to unmask]
Subject: She will love you for this.
Parts/Attachments:

Here's the list config:

* CIT staff discussion list
*
* Confidential= No
* Subscription= By Owner
* Review= Private
* Notebook= Yes,/home/listserv/htdocs/archives/cit-staf,Monthly,Public
* Service= *uvm.edu
* Send= Service
* Errors-to= [log in to unmask]
* Reply-To= List,Respect
* Owner= [log in to unmask]
* Owner= [log in to unmask]
* Owner= Quiet:
* Owner= [log in to unmask]
* Owner= [log in to unmask]
* Default-Options= Repro
* Validate= Yes
* Auto-delete= Yes,Semi-auto
* Exit= UVMEXIT

Serving off is a good idea.  Also, I just thought of putting in a
Filter= Also,[log in to unmask]
statement in this list and another one, but doing this for all 1,400 lists
is a little tedious.
