Domain resolution

I can't figure out how part of name resolution
works when logging onto POP3. Currently, if I don't
put an entry in named.hosts called "mydomain.com."
(with the period at the end) that resolves to my
mail server's IP address, I can't log onto POP3 as
user@mydomain.com. But at the same time it seems
odd that mydomain.com must resolve strictly to the
mail server. And, in examples showing how to set up
a named database, I've never seen a hosts entry
with just the domain name.

Is this domain resolution a function of DNS, or do
I have something else screwed up?

Nope, nothing screwed up. You nailed it.

That is why the convention is to use mail.yourdomain.com
(or smtp.yourdomain.com, whatever) to allow you the freedom
to just use a CNAME for mail, and move it wherever you want.

Perhaps Bind 8 won't have this restriction.  Whats funny is
the MX records will allow mail to come in without that entry
in named.hosts, but won't allow POP clients to check it.
