Hi there,
When attempting to send emails through Thunderbird, I get the following error messages:
Login to server smtp.long-mcquade.com with username X@long-mcquade.com failed.
Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the ‘Authentication method’ in ‘Account Settings | Outgoing server (SMTP)’.
When testing the server connection in server settings and outgoing server settings, I successfully establish a connection, yet I am still unable to send messages.
