Sending of the message failed. The Outgoing server (SMTP) smtpauth.earthlink.net does not seem to support encrypted passwords. If you just set up the account try changing the ‘Authentication method’ in ‘Account Settings Outgoing server(SMTP)’ to ‘Password, transmitted insecurely’. If it used to work but now doesn’t, you may be susceptible to getting your password stolen.
