Here's the summary on my original post was about a mail looping or MX
record points back to itself problem that turned into a recursion problem
everytime I tried to fix the looping:

I want to thank everyone below for answering my plea for help. If
I forgot anyone else, I apologize:

It turns out that the mail looping was caused by having local email
aliases in my /etc/virtusertable as well as the /etc/aliases database.
Before I discovered this, any attempt tto make the server host recognize
that company.net was a local address was thwarted. If I put it in
Cw or sendmail.cw I'd get nasty recursion errors. It was only when I
started fresh with a sendmail.cf file that didn't use virtusertable
that I figured out the problem. I'm still not completely sure why those
local addresses don't work in the virtusertable, but I haven't had time
to take a look more closely.
