I am unable to send emails from Thunderbird. Getting the message: An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Connection from xx.xxx.xx.xxx refused. When I check my password under "Tools - Security', I only see a password listing for my 'incoming' server [that I do not have a problem with]. My out-going server setup has "Authentication" as normal password. When I try to send an email, Thunderbird does not ask for a password. Is it possible the error message refers to lack of a password? If so, is there anyway to manually add an STMP password to Thunderbird?
