I set up a mail server on an Ubuntu 11.04 distribution using the dovecot-postfix package.
sudo apt-get install dovecot-postfix
For some reason, I can't seem to disable non-SSL access through dovcecot. I have made the following edits to the configuration file in an attempt to accomplish this.
... protocols= imaps ... disable_plaintext_auth = yes ... ssl = required ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem
A telnet connection to port 143, however, reveals that dovecot is still accepting non-ssl connections. Where have I gone wrong?
