Thanks Kevin,

I think I have things setup correctly. My existing domain has been working
fine for a couple of years. I recently added the new domain and things
still seem to be fine. My ftp and www are working. I have a couple of
virtual servers (Apache) setup and working also. The problem is with
sendmail. It's not seeing the new domain correctly and someone suggested
that my DNS was the problem.

Can you take a look at my DNS configs and give any suggestions. I'm using
the real names below, not the fakes, home.com and sale.com?

Thanks
