Substitution of Plesk administrated Webserver?

[mrmarkuz (Markus Neuberger)]

There’s a feature request about this and a solution but I didn’t test.
It seems you need to create a pseudouser to have a separate mailbox and then map the right address to the pseudouser.

Multi-domain email server

You need a template-custom and an additional file, please check this gist: then run signal-event nethserver-mail-server-save You can authenticate as pseud01@example.com and become “john”
