Hello!
Email delivery depends from your server configuration. For some cases – you and your subscribers can not receive emails just because email on your server is not working correctly. If you have not received test email – this means that email functionality on your server is not working correctly and you should contact your hosting provider with this issue and ask them to setup email functionality on your server.

Why the problem has only presented yesterday and before he ever worked out?
Also, my host told me that the problem might be due to the emails sent from a generic sender imposed … as a sender “mail@mydomain.com”?
Thanks
