• 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.

Sorry for cross posting, but I'm getting a little desperate.

My server is sending spam--apparently from any domain on the server whether or not the domain is enabled in plesk and from users that are not set up in plesk but only if httpd is running.

I can't find the problem. I've looked in my logs and I get this repeating from mod_security:
PHP:
Apache-Error: [file "/usr/src/build/584794-i386/BUILD/httpd-2.0.46/server/core.c"] [line 3452] [level 3] File does not exist: /home/httpd/vhosts/default/htdocs/blog
But neither of those paths are valid.

I can only stop it by shutting off qmail or httpd entirely.

I've ran chkrootkit and rkhunter and neither finds anything.

ps -fuapache returns a bunch of lines exactly like this:
apache 6327 4345 0 08:55 ? 00:00:00 /usr/sbin/fcgi- -k graceful

I've checked my /tmp dir and nothing looks suspicious in there.

I am at a loss.
