Yes. After doing it I now agree. Maybe that is the reason I see so many
CNAME errors (from other places) in my named log. It is often used
inappropriately.

On another note - what does one have to do to be an MX server for another
site? I suspect just accept that sites mail (CW <domain> or in my case FW 
<externalhostnames>) in sendmail?
