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.

    /usr/sbin/postfix set-permissions seems to fix it

    -rwxr-sr-x root postdrop /usr/sbin/postdrop


    Doing "chmod 2550 /usr/sbin/postdrop" puts it back to failing.
