I am trying to figure out (forgive me if this is the wrong place for this question) how to set up something like Iloha mail or webmailfx.

I see webmailfx is no longer in developement and I'm not sure what to think about iloha - aka tropical.

I am also very noobish in these areas, so please bear with me.

I host my stuff on 1and1.com (I have Developer account) I have multiple domains listed there (out of 11 only two are registered externally). What settings do I need to know/have/install in order for me to set up a mail space for a client to allow them to check e-mail (setup to their domain name eg. fred@client.com) and manage a shared list of contacts.

webmailfx asks for e-mail address? and for username and password for something (in the admin panel) and I am clueless as to what it is asking for?

Anyone out there familiar with 1and1 who could help...I would most appreciate it. I feel soooo lost.
