When attempting to send emails with my server (optusnet), I am getting the message 'An error occurred sending mail. Unable to establish a secure line with SMTP server smtp.optusnet.com.au using STARTTLS since it doesn't advertise that feature. Switch off STARTTLS for that server or contact your service provider.' I have three email addresses and wish to delete STARTTLS and amend my outgoing addresses to 'mail.optusnet.com.au'. How can I do this in Thunderbird?
