If you are still using CentOS 7.9, it's time to convert to Alma 8 with the free centos2alma tool by Plesk or Plesk Migrator. Please let us know your experiences or concerns in this thread: CentOS2Alma discussion
every webmail package that is installed by a controlpanel will always be out of date very soon after the release of that controlpanel. All it takes is 1 single security update to be released.
