1. Is this machine the same one that the rest of the Internet knows as 
"abcworld.com", a.k.a.  dewey.kjpstudios.com? If not, it would be a good 
idea to choose a hostname for the machine that isn't being used by 
someone else.

2. Have you made a custom sendmail.cf file? If so, what changes did you 
make to the sendmail.mc file to generate it?
