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 MyPlesk.com/Plesk360/Platform360 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.

    Had the same problem with latest Obsidian on centos 7.

    The above didn't work and only resolution for me was to edit:
    /usr/share/psa-roundcube/config/config.inc.php
    and add:
    $config['smtp_auth_type'] = '';

    Maybe this change will get lost on the next update so any recommendations would be much appreciated.

    Hi @John Karamatsoukas,

    /usr/share/psa-roundcube/config/config.inc.php should be affected by the updates.

    Ikbel Sassi You need to edit the file master.cf and edit it as shown in the output of the egrep command.
