Right now my Helo Address = localhost (helo=localhost). Is it better to set this to my server's domain name? If so, how do I change it? I'm running Ubuntu 12.04 and Postfix. Thanks.

You can change it in postfix configuration file /etc/postfix/

The helo line is controlled by the smtpd_banner parameter. It probably references the myhostname option. Put your server name there instead of localhost:

myhostname =
smtpd_banner = myhostname

and restart postfix with sudo postfix reload.
