Message Not Delivered: sender account disabled

The message could not be delivered because, according to the sender's email provider email system, the email account for sender's email is disabled. Possible reasons are lack of payment or evidence of a compromised system.


In the sender's email program's account settings, look for "SMTP" (which is about sending email) and then "authentication". Under Authentication, ensure that the username and password for the sender's email account are entered there correctly.

If they are entered correctly and you still get this error, contact the email provider for help.

5.7.13: Official Definition


A permanent failure is one which is not likely to be resolved by resending the message in the current form. Some change to the message or the destination must be made for successful delivery.


Sometimes a system administrator will have to disable a user's account (e.g., due to lack of payment, abuse, evidence of a break-in attempt, etc). this error code occurs after a successful authentication to a disabled account. This informs the client that the failure is permanent until the user contacts their system administrator to get the account re-enabled. It differs from a generic authentication failure where the client's best option is to present the passphrase entry dialog in case the user simply mistyped their passphrase.
