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.
Usually this error related to uncompleted upgrade procedure. Seems Qmail packages were not correctly updated there. Try to switch to Postfix and to Qmail back with autoinstaller or just reinstall all qmail packages with force.
