Okay bugzilla.ade.com doesn't exist on the public internet.

Hold it - a.gtld-servers.net isn't returning data like this any
more.

These servers are the authoritative name servers for ade.com
   AUTH10.NS.WCOM.COM           198.6.100.21
   AUTH20.NS.WCOM.COM          
198.6.100.37

These seem rather large compared to $TTL.

Huh - fortunately this ridiculously large value is ignored by
most sensible name servers.

Only one name server?

MX records should point to A records, not CNAME, make it "IN MX
10 dns.ade.com."

Have you been editting the data to obscure your domain name or
is this a private network?

If a private network I expect the zone is not overriding the
genuine "ade.com", but we'd need more information on how the
client and server are configured for that.
