After I installed Roundcube 1.3.0, I often get this error when trying to open a new email in a folder:
SERVICE CURRENTLY NOT AVAILABLE!
Error No. [600]
Never had those errors before, and I have been using 1.2.x and 1.1.x in many years before. And nothing has changed on the imap side, still using the same version of Dovecot.
Is this a known problem or?
