  • 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.

If you do a telnet mail.yourdomain.com 25

Then if i put mail from : xxxx@xxxxxx.com (a no existing email) and then : RCPT TO: existingemail@domain.com (a email that its in my rcpthosts) , this person can send a message throught the server.

How to solve this?
