Resolution
Create a new Dovecot configuration file in the /etc/dovecot/conf.d/ directory and add all required customization in it.

Connect to the server via SSH.
-
Create a new file with
.confextension, for example:# touch /etc/dovecot/conf.d/my_custom_file.conf
-
Open the file in a text editor and add your custom configuration in it.
-
Restart Dovecot to apply new changes:
# service dovecot restart

Hi. On my server I am trying to make SSL work, since I install a purchased external certificate, but the thunderbird mua rejects me when trying to connect to STARTTLS or SL / TLS.
But watching dovecot.conf I observe that imaps and pop3s do not appear:
protocols = imap pop3
Question: When installing the security certificate on the mail server, shouldn't the protocols be automatically modified by enabling SSL in dovecot?
In maillog I have:
dovecot: imap-login: Disconnected (no auth attempts in 1 secs): user = <>, rip = xxx.xxx.xxx.xxx, lip = xxx.xxx.xxx.xxx, TLS handshaking: SSL_accept () failed: error : 14094416: SSL routines: ssl3_read_bytes: sslv3 alert certificate unknown: SSL alert number 46
Thanks!
