Do your SMTP and IMAP servers support them?
I'm using Dovecot and Postfix. Postfix seems to support TLS and Dovecot SSL, but not vice-versa. I'm wondering what the distinction is when it comes to Roundcube.
In general terms, TLS is the new version of SSL, which is why this UI/terminology is confusing.
