Problems sending email

Does anyone know how to fix problems sending OJS e-mail, what are the possible failures of the application or the server, as it was working normally, now it no longer sends e-mail. For example, even when you try to recover the registration password it does not send. The version is 3.1…2.4

Please send the tool’s email log file.


Are you using ‘localhost’ email server?

Can you upload, for example testmail.php, with this content:

mail('TU@CORREO.COM', 'TESTING MAIL', 'la vida');

And test →

And look your logs.
