• The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Hello,
I have a problem after hacking the server to send spam from my mailboxes.

I have dozens or even hundreds of such processes all the time:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
postfix 12689 0.4 0.0 107076 5196 ? S 08:19 0:00 \_ error -n retry -t unix -u

I get a lot of alerts: lfd on bendlight.eu: High 5 minute load average alert - 6.40
