  • 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.

Question SMTP 550 bounce after 5 days?

Plesk version and microupdate number
18.0.62 Update #2
Hello,

A customer gets a bounce on a 550 SMTP bounce after 5 days. I would say it's normal to get such errors direct? Why trying many days? Is it possible to configure this behavior?

With regards,
Paul
