Faced with the problem that Wordpress has stopped sending any emails. I tried using SMTP, but also could not send emails. Checked in the root folder put the file mail.php and it worked, I received the test letter. This means that the hosting does not block the outcome. MSG. ? Please help with the problem of how to do so I can again send emails through the site. Can provide code on request. PS checked in spam or where it even goes. Just a letter is not coming from the server.
