General plugins (Local): Moodle eMail Test
The Moodle eMailTest plugin is a tool that enables administrators to easily test Moodle's mail system. A trace of the SMTP dialogue will be displayed if the email message cannot be sent for any reason.
Once the test email has been sent, you will need to check your email inbox to confirm that the email message was successfully delivered. This plugin will not do that for you.
