• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Resolved Plesk Premium Antivirus Extension

Premium Antivirus is the default mail antivirus program shipped with Plesk. If an additional license key for Premium Antivirus is not added to the Plesk license key, only 14 mail accounts are protected.

Plesk allows to enable spam protection for any mail account, but only for the first 14 mail accounts. This is the limitation of the free version of Premium Antivirus.

To protect all mail accounts, order a Premium Antivirus license.
