I changed DNS hosts, and it has been multiple hours but I still can't receive emails. I tested with my Gmail every 30 minutes or so to see if it'll start working, but after about 8 hours nothing. The email I send gets bounced back with the following:

Final-Recipient: rfc822; zane@pcnerd19.com

Action: failed

Remote-MTA: dns; mx.pcnerd19.com. (185.27.132.238, the server for the domain pcnerd19.com.)
