This may be giving you trouble:

$ nslookup ennovatenetworks.com
Server:  localhost
Address:  127.0.0.1

Non-authoritative answer:
Name:    ennovatenetworks.com
Address:  63.102.148.71

$ nslookup 63.102.148.71
Server:  localhost
Address:  127.0.0.1

*** localhost can't find 63.102.148.71: Non-existent host/domain

Some mailhosts will not talk to you if your forward and reverse
lookups don't match. I see you are running your own primary DNS host,
so there's a problem there, would be my guess. Lord knows I'm no DNS
wizard!
