Sendmail vs host.domain, featuring DNS


This may be a stupid question, but I all of a sudden realized I had one more thing unresolved that I need to know before I build my new machine tomorrow.

I'm getting a new machine to act as server, and it's going to be headless. I want sendmail to run on it, too.

On my old machine I was able to get sendmail to send mail. But I wasn't able to get it to receive mail.

I have a DynDNS registration. Let's say

or doesn't this affect the working of sendmail?
