Using email on the same domain on a Ghost installation on YunoHost

https://postcrescita.it is a wonderful #Ghost website curated by @ceci+comrades. It’s hosted on my community #server, powered by @yunohost.

How can I provide them one or more #email addresses using @postcrescita.it, that they can regularly use through a mail client, without compromising Ghost’s (required) email functionality?

Here is the related thread on the YunoHost forum.
