hello!
every day i receive an email with that subject and this body:
> This is the mail system at host [mms.nohost.me](http://mms.nohost.me).
> I’m sorry to have to inform you that your message could not
> be delivered to one or more recipients. It’s attached below.

> \<[admin@mms.nohost.me](mailto:admin@mms.nohost.me)\> (expanded from ): user unknown
it seems like it is addressed to the new “admin user” created with the latest update, right?
however, i cannot create and email address for the admin, but yunohost is trying to send it email notifications (guess regarding diagnosis?) anyway?
what can/should i do?

That’s a bug in the current testing that needs to be fixed, we need to properly re-define the admin@domain.tld aliase(s)
