this post is similar to the many discussed few days ago but that does
not answer to my question.
In my previous post I would like to know if exists a solution to use
zimbra for an internal lan, and setup it with a dumb domain so that
the users could use it to exchange messages between them, and
eventually make an individual setup for users that want to download
mail from their real pop-3 account, post, and work in this way.
Now I would like to know if is possible to try a different solution,
as asked in another thread in these hours (but the conversation
moved to try the fqdn installation): i.e. do not use a domain
at all, and identify internal users only by their username.
Is this possible?
