Actually in Outlook Express, you didn't need to specify the server name, just specify the IP address of your server in the incoming and outgoing server. This should be work fine.
But if you want to know what is your hostname is try to look it into /etc/sendmail.cf and found the line Cwblabla (blabla should be your domain or your server name), but if you found Cwlocalhost instead of Cwsomedomain.com, you probably need to go to /etc/sysconfig/network
