About 2 weeks ago, I stopped being able to 'send' from Thunderbird, although directly with ShawMail was OK. I have found two solutions that allow me to send from Thunderbird. Thunderbird indicates that the defaults recommended on their set-page come from Shaw. So from Shaw's POV, which is less bad? (a) or (b)?
I prefer to use the SSL/TLS option for security. But my choice is between (a) overriding the default port vs (b) using StartTTLS for out-mail (with SSL/TLS still for in-mail).
a) SSL/TLS for both In and Out-mail .... In-mail port 993 (default) ... Out-mail port 587 (requiring override of default 465)
b) SSL/TLS for In-mail ... In-mail port 993 (default) ... StartTLS for Out-mail ... Out-mail port 587 (default)
