[Kroupware] kolab components -- standard or modified from originals?

[Andrew Kohlsmith]

I was hunting around the kolab web pages but I couldn't find an answer to my 
question.

The kolab components: apache, postfix, cyrus, inetd, proftpd, openldap -- are 
the packages on the FTP sites any different than the packages I would get 
form the respective software's home page?  

I imagine that there are configuration changes, but are there any actual code 
patches or differences in the code from the original software?  If so, where 
do I find the changelogs or diffs?

Regards,
Andrew
