If you want it, set this in dovecot.conf: disable_plaintext_auth = no Basically dovecot is taking the secure approach by default. If the client is connected without encryption, then they should not be sending a plaintext password, as it's easily sniffed. The above config removes this policy. Or: try making an encrypted (imaps) connection, like this: openssl s_client -connect 127.0.0.1:993 HTH, Brian.
