my smtp server is not allowing mail to send. here is the message i get when attempting to send new messages:
Sending failed:
Your SMTP server does not support The server responded: “Incorrect authentication data”. Choose a different authentication method. The server responded: “Incorrect authentication data”
The message will stay in the ‘outbox’ folder until you either fix the problem (e.g. a broken address) or remove the message from the ‘outbox’ folder.
The following transport protocol was used: myaccount.com
Do you want me to continue sending the remaining messages?
Authentication is set up as Plain.
anybody understand what is going on? what do information do you need, and how can i remedy this situation?
