I installed the plugin and it works on accounts with usual gTLD's. But I have one account with the new gTLD .EMAIL, but there I get this message when I click Email Level Installer:
Make sure you've entered a valid domain name.
I'm confused as to what you're asking.
Are both servers running DirectAdmin? The plugin will only work on a DirectAdmin server.
Are you asking if you can host the email on a different server from where you're hosting your website? That's got nothing to do with the plugin.
Just what are you trying to do?
And yes, the plugin can connect from server A to view E-Mail info on DA server B.
You'd edit the config from localhost to the other server hostname.
Must be a DA box.
The plugin *only* uses DA, it does not connect to IMAP or POP for it's information.
