Is there way to disable plaintext managesieve protocol from dovecot and support only ssl version? how? Well, first of all, unlike imap/imaps, there is no managesieves protocol that has SSL from the start. ManageSieve only uses TLS, as initiated with the STARTTLS command. Like for IMAP, the use of TLS can be forced by setting disable_plaintext_auth = yes. Then, the client cannot authenticate until it has established a TLS security layer. Note that this setting will not have an effect when you are connecting from the local host.
