So, I am setting up some forum software on a VPS server I have rented
and would like to invite users to have access to the forum *and* an
email account, but nothing else.
I have dovecot set up, and make roundcube available as the web-based
mail client.
The only thing I know to do is to add them as a user, which basically
gives them a shell, and I'm not enthusiastic about that.
I hope I do not misunderstand your requirements. You need not set up a system user to
allow mail usage. You just create all your mail users in dovecot (/etc/dovecot/users)
using doveadm and configure postfix to authenticate against dovecot (virtual mailboxes in
postfix speech). The mail ist stored at e.g. /home/vmail/<domain>/<user> and
everything is managed by dovecot (vmail being the dovecot process owner).
