I’m trying to do the mail test, but the message isn’t received if the domain is different of the mine. For example, I receive all the messages in the “example@woliverio.blog.br”, but if I put the mail address “example@hotmail.com” or “example@corporate.com”, the message isn’t delivered.
When you set those addresses as SENDER addresses? Or receiver? Anyway, mail problem should firstly reported to the provider, maybe they have some filters active.
