DNS was hosted with XO, no control options for us. They wanted the SOA
to be with them so that their system could dynamically change IPs of
pop/pop3/smtp/mail/www.ourdomain.com whenever their cluster IPs changed.
This typically happened once a week and I then had to track what IPs
changed and then make appropriate changes to our internal DNS.

Also, while the change was happening, we experienced intermittent
refused connections for outgoing email which obviously XO wont accept
even when I sent a copy/pasted telnet session to port 110.
