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
