I know that zimbra provides mail server etc etc.
I installed it before (over a year ago I think) and noted that it wants to use it's own postfix/ldap etc. and thus decided not to use it at that time.
I have set my infrastructure up how I want it.
I do not want to use zimbra for address books etc. as I already have an ldap/kerberos address book/authentication that works well for my client.
So the question is, is it possible to integrate zimbra into an existing framework.
I'm quite happy to spend time and pain doing it.
Does anyone have experience of doing this, I'm not necessarily asking for help - I just don't want to waste a week of spare time doing this if it doesn't work.
