I see the .com is now using godaddy's servers, it looks like you've set it to redirect to matrixcabparts.net which is using Linode's name servers however it has two A records
Code:
matrixcabparts.net. 600 IN A 45.33.54.100
matrixcabparts.net. 600 IN A 184.168.221.46
The 184 record is a godaddy IP and should be removed.
The .com has MX records which point to
Code:
mailstore1.secureserver.net. 31 IN A 72.167.238.32
smtp.secureserver.net. 30 IN A 68.178.213.203
Which I assume is correct.
The .net has MX records which point to
Code:
matrixcabparts.net. 600 IN MX 10 matrixllc.build.
matrixllc.build has no dns records so mail won't be delivered for the .net domain
