I will be starting have started setting up a new mail communications server to move to something a little more independent than Google
the server should have:

email support
frontend / web login
smartphone interface / app
calendar
addressbook

owncloud! see dropbox

then there should be
irc
disapora
xmpp > ejabberd or prosody
config: http://wiki.ubuntuusers.de/ejabberd
https://prosody.im/doc/install

backup MX and rsync to some other server must be there

zimbra open source edition looks nice
webmind offers puscii
>> iredmail with squirrel and/or roundcube
