Don't know if it matters to the resolver lib, but the format of the
hosts file (from man hosts)

IP_address canonical_hostname [aliases...]

i.e. 192.168.1.1 smtp.mydomain.com smtp smtp1

I'm not running FC7, but every FC release I have used in the past has
always configured sendmail to only listen on localhost out of the box.
So you might need to edit sendmail.mc to have sendmail also listen on
eth0.

To override sendmail from using DNS lookup for your domain name and
force e-mail to be delivered locally without "relay=public IP", I would
suggest that you read about implementing the "mailertable" feature in
sendmail.mc. As others have stated, you would also edit
/etc/local-host-names as you have already done.

i.e. mailertable entry

mydomain.com esmtp:[smtp.mydomain.com]

-or- maybe something like
mydomain.com esmtp:[127.0.0.1]
