  • 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.

How do I downgrade?

Hi,

I upgraded to 8.6.0 and since that moment Qmail is not sending messages. It's usually "451 qq read error" and then immediately "502 Unimplemented". I have applied every single patch and workaround I have been able to find, have restarted psa and qmail every time I have applied those patches, etc. but I still get the same errors.

When trying to upgrade to a 9.x.x version, the system does just nothing, all I can see is the usual message with the green tick. After a while, nothing happens, also nothing happens after the "service psa restart". And no mail received, of course - see above.

So, how do I downgrade to the previous Plesk version (8.2 I think it was), I think it's the only sensible solution.

Thanks.
