Reindl, you really need to learn how not to be such a total ass.

How precisely do you equate 'not *exactly* the same', and there is a 
'big difference'.

Again, there *is* a technical difference, albeit minor:

Anyway, as usual, Timo is spot on... Thunderbird has the choice of 
'SSL/TLS', and I imagine it is because TLS uses stronger encryption 
algorithms (which I just learned) that Dovecot uses it when given the 
choice.

Now the only other question is, again already being contemplated by Timo 
apparently, why the config file uses SSL...

Timo, what I would suggest is allow the use of ssl in the config file 
for backwards compat, but change future versions to use TLS...

I'm curious though... I'm fairly certain that my Android phone 
differentiates between SSL and TLS, with choices something like:

NONE
SSL if available
SSL Always
TLS if available
TLS Always

And I always choose (chose - from now on I'll choose TLS) 'SSL Always', 
so shouldn't these connections show 'SSL' instead of TLS, since I'm 
basically forcing my phone to SSL?
