My question now after it appears to be working, did I configure this properly for TLS? Users can still log into the IMAP server and get their mail via plain text or with the SSL certificate. Did I set the correct port for ssl_listen or is that for SSL only and not TLS?Comments / Suggestions?
If you want to have all protocols enabled add the following line in your dovecot.conf
protocols = pop3 pop3s imap imaps this will enable "normal" pop3 and imap connections too. Nicolelli Federico
