You don't need a MX record. BUT you *should* have a record in the
/etc/hosts file. I'm assuming you do have an Ethernet card (just not
connected to anything at present), so you need a line like the
following in your /etc/hosts file.
192.168.250.1 sauron.deepsoft.com sauron
replace '192.168.250.1' with the IP address you configured your
Ethernet card to and 'sauron.deepsoft.com sauron' with
'mymachine.domain.com mymachine' (assuming mymachine.domain.com is your
hostname).
