In the Thunderbird 3 SMTP configuration dialog, there's a security section:
If I want to send email without naughty hackers intercepting it, what should I choose? The "Connection security" options are "None", "STARTTLS" and "SSL/TLS" - which is best?
Do I need an authentication method, or is that just for the mail server to know who I am? (if so I don't care about this, since I can already send email without problems.)
