No more notification emails

It could be a plugin conflict as many were recently updated for security reasons and compatibility with WP 4.2.2

Or it could be an issue with your hosting provider.

Hope this helps.

Yes it was a cPanel issue, because our emails are not hosted on the same server as our website. Here is the results if anyone else needs, just in case. It may also only happen because of multiple sub domains and 2 sets of DNS… But this may still help someone…

Since email for yourdomain.com is hosted elsewhere, you will want to disable local mail service to prevent your “new-yourdomain.ca” cPanel server from attempting to deliver mail locally. To do so, log into the cPanel for yourdomain.com on that server and click “MX Entry” in the “Mail” section. Now choose “Remote Mail Exchanger” in the “Email Routing” section, and save that change.

P.S. This plugin is great!

That’s great that you were able to resolve the issue.

Thanks for posting your details.

I am sure this will help others that may experience a similar issue.

Another work around that may prove better in the long run is to install/use
WP Mandrill that’s listed as one of our recommended plugins for Job manger
