• 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.

Plesk 12 has big problems with email and POSTFIX

Hi! It's time to fix issues with postfix in Plesk 12.x. Our production servers (and so our customers) have many problems with email. This is not acceptable.
The Parallels team should definitely fix the bug.

The issue is related to "localhost" helo. PHP mail() and other non_smtpd services use "localhost" as HELO string. Plesk 12.x f blocks messages presented with localhost helo. We had to skip non_smtpd_milters in main.cf of postifx, in order to let the messages to be sent. But this workaround excludes psa-pc-remote from milters skipping all plesk filters (including DomainKey signature) in the server-side generated mails, causing them to be marked as spam without domainkey.

Please let us know asap.
Thank you very much.

Hi,
More than 5 months later and there is no fix for this issue.
It's a serious problem and it's still persists!

Parallels has to do something quick!
