Hi there, Even after reading documentation, I am unclear on these two options: tls/ssl or starttls. And what does it mean as to port# that client should use to connect to?
The confusion comes when I set up a mail client (e.g., Thunderbird). I see these two options for both incoming and outgoing SMTP server. Depends on whether I specify startls or tls/ssl, the port# client connects to the server is different. On the incoming server, I use POP. If it is over TLS/SSL, it is 995 (secure POP). But if it is STARTTLS, it is 110 (default POP), is it still TLS/SSL enabled? Why is that? Which one should I use: starttls or tls/ssl for secure connections? I thought enabling "starttls" indicates that client and server will announce they support TLS before any AUTH data is sent over. But is subsequent communication secure? And, if I simply enable "tls/ssl", does that mean AUTH data is sent in plain text but any subsequent communication is secure?
