1- Authentication failure: If you are unable to connect to your account despite entering the correct email and password, you can now see error 550 on the screen. But apart from that, you won’t be able to read your email account’s emails. The issue may be with SMTP authentication. If your email is not configured properly for SMTP, you are more likely to receive error 550. To stop their email accounts from being hacked by hackers or spammers, email service providers only allow SMTP authenticated users to send and receive mail on their servers.

Follow the Instructions below to Allow SMTP Authentication:

  • To allow SMTP, go to Mail settings and select ‘My server needs authentication.’
  • If you use Microsoft Outlook, this will happen automatically.
  • Simply click ‘Yes,’ and the software will be installed.

2- Sending emails from the wrong address: Entering the wrong email address in the ‘From’ area would result in a ‘Unauthorized sender’ message or a ‘Response server error.’ In this case, the receiver can reject your message and return it due to an authentication failure. On the other hand, the server would block all mail addresses that have not been checked or authenticated by it. This is a troubling and irritating problem.
