Hi all,

https://doc.dovecot.org/2.4.2/core/summaries/settings.html , the auth_allow_cleartext section, says "If no, disables the LOGIN command and all other cleartext authentication unless SSL/TLS is used (LOGINDISABLED capability) or the connection is secured (see ssl).

See SSL configuration for more detailed explanation of how this setting interacts with the ssl setting.

This setting replaces the disable_plaintext_auth setting."

I put auth_allow_cleartext = no in my 2.4.2 dovecot.conf, but my Claws-Mail client can still access it, even though there are no key files. I tried putting this setting in several different places: Didn't prevent plain access. I tried switching from 127.0.0.1 to 10.0.2.15, same problem. The following is the output of my dovecot -n command:

=========================================

2.4.2 (0962ed2104): /etc/dovecot/dovecot.conf

dovecot_config_version = 2.4.2 dovecot_storage_version = 2.4.2 listen = 10.0.2.15 log_path = /var/log/dovecot.log mail_driver = maildir mail_gid = vmail mail_home = /home/slitt mail_path = ~/mail/Maildir mail_uid = vmail protocols { imap = yes lmtp = no pop3 = no } service imap { inet_listener imap-login { auth_allow_cleartext = no } } namespace inbox { inbox = yes separator = / } passdb pam { driver = pam } userdb passwd { driver = passwd }

How do I disable plain text authentication?

Thanks,
