It resolved to 67.54.156.70, but now I'm not getting any resolution.

Using a second domain name, just for it, makes it easy should you, at some time, decide to have your mail handled by a different machine than whatever handles your webserver. Whatever domain name you use for your mail, whether that be mail.pilotalk.com or just pilotalk.com, you should have a MX record for it in your domain records. How MX records are used: Someone tries to send a message to test-person@xxxxxxxxxxxx, their mailserver looks up the MX record for pilotalk.com to find out how to reach your SMTP mailserver. Their mailserver connects to the MX record's address to deliver the mail. If it can't do so, it tries to send to the next MX record address. And walks down the list of MX record addresses until it can. When it finds one that accepts mail, it sends, and that backup mail server will eventually pass the mail onto your mail server, as soon as it can. You have no MX record. Systems presume that they can use pilotalk.com as the SMTP server, that may or may not be the case. If your server is down, you cannot get mail. And people cannot even try to send you mail. -- [tim@bigblack ~]$ uname -ipr 2.6.22.1-27.fc7 i686 i386 Using FC 4, 5, 6 & 7, plus CentOS 5. Today, it's FC7.
