  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • 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.

There is no SPF record in the DNS of the hostname (srv2.jcwebdevelopments.co.uk) of your server. That leaves your server being vulnerable for abuse. The hostname can easily be used for email spoofing by anyone. Add a strict SPF record asap.
