On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

    Hi. On my server I am trying to make SSL work, since I install a purchased external certificate, but the thunderbird mua rejects me when trying to connect to STARTTLS or SL / TLS.

    But watching dovecot.conf I observe that imaps and pop3s do not appear:

    protocols = imap pop3

    Question: When installing the security certificate on the mail server, shouldn't the protocols be automatically modified by enabling SSL in dovecot?

    In maillog I have:

    dovecot: imap-login: Disconnected (no auth attempts in 1 secs): user = <>, rip = xxx.xxx.xxx.xxx, lip = xxx.xxx.xxx.xxx, TLS handshaking: SSL_accept () failed: error : 14094416: SSL routines: ssl3_read_bytes: sslv3 alert certificate unknown: SSL alert number 46
