I'll work on fine tuning the server once I get mail working and backups installed.

As for criticisms of my line lengths, I'm using webmail from my ISP (Verio). Help me get my server up and I'll be sure to religiously follow protocol.

Back to the topic at hand though, I just got some bounce messages from attempts to send mail to my server: "451 Name server timeout"

======================================================
- The following addresses had transient non-fatal errors -

451 grayrunlevel6.com... runlevel6.com: Name server timeout
Warning: message still undelivered after 4 hours
Will keep trying until message is 5 days old
======================================================

As my BIND is newly installed also, it could potentially be a DNS issue. Dnsreport.com gives me a warning that may be relevant:

WARNING: One or more of your MX records did not return an A record; most likely, they have a CNAME. CNAMEs are prohibited in MX records, according to RFC974, RFC1034 3.6.2, RFC1912 2.4, and RFC2181 10.3. The problem MX records are:
smtp.runlevel6.com.->runlevel6.com.->66.159.220.130

Ideas?
