Thanks for your feedback......

I use 143 and if using 993 tell the system the the Certificate are wrong ??? You are using a self-signed certificate and the certificate. That is ok, you need to make outlook accept the certificate. I don't know outlook but maybe you get a message and can accept the certificate?

For a secure connection on port 143 enable the use of starttls in your outlook account, this way encryption is enabled after the initial connect to dovecot.

Connection to port 993 (imaps) is encrypted from the start and secure too.

To get rid of the certificate warning you need a proper certificate from e.g. lets encrypt

Hello

Debian, with postfix and Dovecot Imap "2.2.13" running.

If I want connect from Outlook or Thunderbird I will become this error: Plaintext disalowd on non secure SSL/TLS Connection.

but I will that this run with secure connection, I don't have any intention to use Plaintext auth.

How is your Outlook account set up? Which port is configured in your Outlook account? Port 143 using starttls or port 993 ssl?

...

Also I don't know why, dovecot will switch from IMAP --> POP3-Login. Or it's this Outlook that will ask for it.

Dovecot does not switch from imap to pop3. Your Outlook seems to be configured for pop3 access.

10-ssl.conf

            SSL = yes

10-auth.conf

disable_plaintext_auth = yes

Mail.log

pop3-login: Info: Disconnected (tried to use disallowed plaintext auth): user=<>, rip=IP, lip=ip, session=<bnmZNB1AUZ+Blw>

Provide the output of doveconf -n for better help.
