• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is 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.

Users getting bounced mails from recipients they never sent to

Hi guys,

having queer situation nowadays

my users are reporting receiving bounced mails from users they never send to.
Example, [email protected] sends a mail to someone, either internally or external domains say, [email protected]

user from domain1 will receive a bounced mail for failed recipient mail to [email protected] - for the same mail! even though the user didn't send to this person.

And it is happening across all my domains users, which are situated in different geological locations...

i did thought of a computer being spyware-d, but so many users at the same time....

anyone?
