Multiple accounts on a box

Does Mail in a box support hosting email accounts for multiple people, or is it designed to just service an individual user? That is, could I have and served from my box?

Taking that one step further, is it possible to configure aliases along the lines of /etc/aliases in Postfix?

It can host mail from as many accounts and domains as you like.

I’m currently running 5 or so domains with maybe 30 or so accounts across them.
