• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service.

  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Issue Plesk Email Notifications (two Content-Type headers)

P

Paul Hermans

Basic Pleskian
The Plesk Notifications system sends out email with wrong syntax: two Content-Type headers, we get the following error message from our SMTP server:

Error: 550 Messages should have one or no Content-Type headers, not 2. (in reply to end of DATA command)

Email notifications are not devlivered anymore.

We upgraded Plesk from Onyx to Obsidian then after a recent Obsidian update I believe this problem started.
