Cached values from a lookup I did 2 hours ago:
Code:
% nslookup -type=mx grantpalin.com
Server: 10.0.0.134
Address: 10.0.0.134#53
Non-authoritative answer:
*** Can't find grantpalin.com: No answer
Authoritative answers can be found from:
grantpalin.com
origin = ns1.linode.com
mail addr = grant.grantpalin.com
serial = 2015042066
refresh = 14400
retry = 14400
expire = 1209600
minimum = 86400
I note that asking ns1.linode.com directly gives me a single MX and a higher SOA. So that makes me thing you made a change recently.
If you have recently made the change then you need to wait for it to propagate across the net, perhaps up to 24 hours.
