Issue Failed to determine Webmail via command line

[Jhow Plug]

How to set the desired type of webmail via command line?

I've tried the command plesk bin mailserver --update-webmail mewebmail -state true

But it does not work.
I want to know what is the command line for Set host by host, ie a command line for each domain

Thank you
