"Caused by: javax.mail.MessagingException: Unknown SMTP host: dandcserver.net"

su - zimbra

hostname

zmhostname

ifconfig

cat /etc/hosts

I get SERVFAIL when trying to resolve your domain, further investigation shows the DNS Nameserver:
DNCSERVER1.DANDCSERVER.NET (66.24.107.60)
Doesn't respond to DNS queries. A reverse lookup on the IP address shows this is actually a roadrunner ip address, which I don't think they allow DNS servers on private connections.

not only that, but the other nameserver doesn't seem to exist:
[zimbra@support01 ~]$ dig any dandcserver.net
