Postfix SASL auth fail

[RolandG]

Hello there! I've just setup CentOS 6.6 with Plesk at my Hoster OVH. Now when I want to connect to the smtp server I get following message:

SASL LOGIN authentication failed: encryption needed to use mechanism

SASL auth is enabled in the main.cf also submission. I connect to tls://smtp.example.com:587 with my email and password.

What sort of output of following command:

# postconf -n | grep smtpd_sasl
