How To Fix ‘Error 550’ Or ‘Unauthorized Recipient Error’ In Roadrunner email login page?

 

Seeing ‘Error Code 550’ or ‘Recipient not authorized’ in response to a sent email could have many reasons behind it, which we will now discuss one by one. The problem is quite prevalent in Roadrunner Login/Email, so our solutions will be based upon that particular email service.

1. Authentication failure: If you are not able to fully access your Roadrunner email login page account despite having entered the correct email ID and password, then there is certainly some problem with the email account. Problems could be anything, such as unable to send and/or receive emails, so if you think you are dealing with this problem, then that’s because of ‘Error code 550’. The problem may have sourced from SMTP authentication. When your email account hasn’t been properly configured with SMTP authentication, then you will see ‘Error code 550’. Companies in the wake of protecting their servers from spammers and hackers are only allowing their customers to use SMTP authentication. As an email user, you will have to check the ‘SMTP authentication’ box to verify the process. To do so, here is what you are going to do:

• Go to email settings followed by clicking box ‘My server wants authentication’ to turn on SMTP.

2. Sending emails from a wrong email address: If you have been sending emails from a wrong email address then you will get an unauthorized sender error or server response error. The recipient will not be able to recognize as to who sent the message, and thus, will reject the same. The server will block the email if the email address turns out to be invalid. Then, you can’t send emails to anyone. To fix that issue, here is what you will have to do:

• Check whether the email address has been properly written during the email account setup or not. Maybe you have made some alphabetical mistake.
• It takes around 24 hours to activate a new email on the server.
• While creating an email account, pay attention to the special characters because most people make mistakes will entering special characters.

3. Sending emails to a non-existing email address: If you send emails to a non-existing email address, then it could cause problems like the one we are discussing here. If your sent emails have returned to your inbox, then it confirms that the email address that you’ve entered is wrong. Here is how you can rectify this problem:

• Check if the email address that you’ve entered is correct, and doesn’t have any spelling error.
• Also, make sure that there isn’t any problem with the recipient’s email server.
