• 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 Obsidian 18.0.79 on CentOS 7.

Native Plesk mailbox forwarding of externally received messages from
[email protected] to local mailboxes is rejected by the local
Plesk DMARC milter after SRS rewriting.

The original incoming message passes SPF and DMARC and is delivered to
[email protected].

Forwarded copies are reinjected from 127.0.0.1 with an SRS envelope sender.
The Plesk DMARC handler reports:

spfres=pass
dkimres=pass
align_spf=fail
align_dkim=fail
p=REJECT
dmarccheck=DMARC_POLICY_REJECT
dmarcstatus=STOP

Postfix then reports:
milter-reject: END-OF-MESSAGE from localhost[127.0.0.1]:
5.7.1 Command rejected

mail_dmarc_reject_at_smtp=true is already enabled and
plesk repair mail -y has been completed.
