I think sendmail will ask DNS for an MX record first because that's how mail is supposed to work - then if that fails it goes for an A record or your hosts file.
Sorry - missed that one .
nslookup cnn.com comes back fast.
if I do nslookup mymachine.domain.com it comes back with error.
How do I make this resolve faster or something. I have no way to make an MX record for this box. its all just local email. it never leaves the box.
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).
