Hello @ahmadbintariq4u

This exception has to do with Java mail not able to communicate with Mailtrap. You should check your Mailtrap config, the email port is usually 2525 and the username and password are usually alphanumeric and not your Gmail account

@SeunMatt Thanks bro. one more thing.. Is the EMAIL_FROM && EMAIL_TO is the gmails?

SeunMatt commented 3 years ago

The EMAIL_TO is the email where the zipped backup files will be sent, it can be any valid email - Gmail or others. The EMAIL_FROM can also be any valid email address.
