Terminology. SSL has several versions: SSLv2, SSLv3, TLSv1. All are considered to be Secure Sockets Layer, with the last one being the most current version. I think what some folks think of when they hear "TLS" is the more modern way of negotiating an SSL/TLS connection via POP's STLS or IMAP's STARTTLS or SMTP's STARTTLS commands. Whether you use an "SSL" port (e.g. 465, 993, 995) or a non-SSL port (e.g. 25, 587, 143, 110) and negotiate "SSL", you are likely using
TLSv1.Thanks for the explanation. Sounds like Thunderbird's "TLS" setting
probably means to try STARTTLS, rather than use TLSv1.
That's true and it's the same for SMTP - and it's not the best possible I think. If you're interested in what lead to that naming, read through https://bugzilla.mozilla.org/show_bug.cgi?id=135357 (interesting part in respect to UI starts around comment 100).
