I look for a way to enforce a lamba user to connect to dovecot server with TLS.
I followed the documentation http://wiki2.dovecot.org/SSL/DovecotConfiguration , and I edit the dovecot configuration as follow :
ssl = required
disabled_plain_text = yes
Then I reload and restart dovecot.
Then I connect to the dovecot server by typing telnet localhost 143.
But I can connect to a mailbox user again (by typing a login toto password) whereas dovecot should inform me to use tls before.
An idea ? Thanks in advance, cordially.
