• 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.

Making reverse lookups work

well, this might not be plesk related -- but I don't know where else to post it.

I used to get the "possible break-in attempt" error when logging into SSH. Apparently the ISP has fixed this (for the moment) -- but it'll probably be back tomorrow.

One thing that's still "broke" is email. Any external email addresses receiving mail from my server will show my IP address "may be forged" in their headers.

Received: from server.example.com
(ds209-253.ipowerweb.com [xxx.xxx.xxx.xxx] (may be forged))
by ...com (Xserve/smtpin20/MantshX 4.0) with ESMTP id ...

how do I make the "may be forged" go away?

Are there any other areas I should be looking to fix regarding this reverse lookup thing?
