  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • 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.

prevent forging SMTP header

Hi there,

Does anyone know if is there a possibility in plesk to prevent authenticated SMTP users from forging the 'From' field of email header?
Now it's possible for every user that had successfully authenticated to use any address in 'From' field. I'd be great if there's an option in plesk to restrict user to use only hi login name or alias/es in 'From' filed
