Bill,
 
1. 1.5m will tell you why it rejected the mailfile.
 
2. I have already explained 200 times why I have to look into the body
   of the mailfile, and I'm not going to explain a 201th time. Just set
   your list to "Loopcheck= NO" to bypass all loop checks, and enjoy.
   It won't be long until you revert to the totally incorrect behaviour
   of looking into the header.
 
Eric
