• 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 problem with fake email address

Sorry to write that, rout3rx, but I find it a bit confusing, that you received so much solutions and hints in this thread, but none of them ( exept the last one and the one for "reject_unauth_destination" ) seem to reach it to your configuration files. Pls. don't be surprised, when your issue doesn't change.

Consider to start again to read and follow the suggestions and pls. report back only with depending log - files entries ( if you changed your configuration files, then pls. add them again to your next post, so that people willing to help you have the possibility to investigate the possible issue(s) ).

At the moment, I just notice another misconfiguation at:
smtpd_sender_restrictions = check_sender_access hash:/var/spool/postfix/plesk/blacklists, permit_sasl_authenticated, reject_authenticated_sender_login_mismatch,
 
Hi, i added all of the configurations that explain in threads in another server, but mr dash says, i check the reject_authenticated_sender_login_mismatch on the raw and fresh postfix configuration.
i has been removed "," at the end of smtpd_Sender_restrications but, still i can send email with [email protected] !
are you set this configuration? and fix this?
