ok...
If you install uvdesk under Plesk solution, even if you install MailParse in php version (I use php 7.4)

https://support.plesk.com/hc/en-us/articles/360005875373-How-to-add-additional-PHP-module-for-PHP-engines-shipped-with-Plesk-on-Linux-

You must enable into domain site -> php version
at the end you can put additional configuration, I don't know why the installation not activate the module and only the additional configuration enable it...
