• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service.

  • 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.

I'm not sure if this is a plesk related issue or not. I just transferred a domain from one plesk server to another, now I'm getting bounces with the following error:

Your message cannot be delivered to the following recipients:

Reason: Illegal host/domain name found

Any ideas what this is and if plesk is to blame? I checked all the comprehensive blocking lists I can find and none of them have the domain listed. I'm stumped!
