Do you use godaddy provided email system, if so ask them is the email firstname.lastname@example.org is configured for a new server and available.
If you want to use the server email. Let me know i can adjust the MX to make it working
the domain MX record was resolving to an third party Email service provider “secureserver.net”. So, There will be no logs generated in server regarding Mail transaction of the domain “voip.us”
so check back with the email service provider of “voip.us” where you have pointed the MX record.
MX Records :
voip.us. 3599 IN MX 10 mailstore1.secureserver.net.
voip.us. 3599 IN MX 0 smtp.secureserver.net.
A record for MX records
mailstore1.secureserver.net 126.96.36.199 188.8.131.52 184.108.40.206
