[CentOS] web based mail packages for CentOS

Ed,

I saw no activity though the sac queue (I kept refreshing) but no luck. 
I had created 2 users in SAC to hopefully catch all of the mail that I 
was no longer recieving while I was trying to get the kerberos going... 
I believe what could have been the cause is: 1 the post I read on 
setting this up wasn't correct or some part of the process was not the 
same 2) I configured scalix to authenticate against the kerberos. So 
when I tried to logon I kept getting rejected as password or userid not 
found 3) not understanding what I am getting -> do I have to create an 
account and 'tie' it to the kerberos?

The sendmail was rejecting to my userid even though the user existed on 
both the sac and AD, which supports my idea that it's not 
'authenticating' with the AD server...

As I mentioned sendmail isn't my favorite but I did run for some time 
before moving to postfix. From what I've read scalix takes care of this. 
Are there any post install scalix scripts that I have to run?

I see that there is a component called Scalix ForestPrep. Is this 
included in the open source distro? I would prefer this if possible. A 
single sign on is ok if that's all I can get but having true integration 
with the directory server would be preferable as I would like to have a 
single entry for ease of admin.

The docs and knowledge base do not really talk about it, which makes me believe that this thing should be working out of the box.
