I can send and receive mails using: IMAP 143 with TLS

OK, IMAP STARTTLS is working in some sense. (Your MTA handles SMTP, not dovecot.)

The hangup occours inside of my LAN using Outlook 2016, and Outside also trying access on 4G from my Android smartphone.

My goal is enable also POP3s and IMAPs using TLS.

I can't really see from what you present what the problem is. Can you report the output of

openssl s_client -starttls imap {imap-server}:143
openssl s_client -starttls pop3 {imap-server}:110

(from both inside and outside), as well as any matching log entries.
