I'm sorry, I'm new to dovecot, it seems my terminology is all wrong :-)

I assumed pop3s is pop3+ssl is pop3 over ssl.

In my config file (just an excerpt):

protocols pop3_listen pop3s_listen 
elag.hr is my domain name. It resolves to the current external IP address.

So when I connect from outside, my email client asks me to verify a ssl
certificate. This enforced me to believe pop3s is pop3 over ssl, or as I
called it above pop3+ssl.

If I'm wrong, what is pop3+starttls?
