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 Tony,

    I tried to reproduce the issue but I could not. All good on my server.

    Please try "plesk repair mail" via ssh or open a ticket with us if the issue persists.

    After running the query above on a fresh plesk install with this sendmail outgoing permissions issue I'm seeing an error when enabling email on a domain using the plesk UI.  Be sure to take seriously the instruction step to make a backup of the db file before proceeding!

    Error: mailmng-outgoing failed: ERROR:__main__:UNIQUE constraint failed: domains.name

    I don't think this issue has been fully fixed. I just encountered this issue my server with Plesk version 18.0.33.

    I made a cronjob on all Plesk servers with the script from above, because it's happening over and over again

    I need to use this workaround for every new subscription. Plesk is up-to-date.

    Are there any other solutions on this topic?

    Hi there!

    The bug mentioned in this article was fixed in Plesk Obsidian 18.0.28 but it might be possible that the consequences of this bug are present on newer Plesk versions.

    Stefan Wolf If this issue is encountered on newer Plesk versions, apply the workaround available in this article. In case the issue persists after applying the workaround, please submit a ticket to Plesk Support to investigate this issue further.
