[BBLISA] zimbra, exchange, etc

[Sean Lutner]

I implemented Zimbra as a corporate mail/calendar/etc at the last  
place I worked and it was a workable replacement for Exchange though  
it wasn't without it's issues.

At the time all the Windows folks were running VIsta and Outlook 2007  
and I was forced to use a beta version of the Outlook connector. The  
connector kept Outlook and the ZImbra server in sync for mail, GAL and  
calendar. It allowed free/busy functionality once we replaced the self  
signed cert that Zimbra provided that Outlook wouldn't trust.

As previously mentioned it's quite a resource hog. The mailstore/IMAP  
portion of the system runs out of Tomcat and MySQL + Lucene are the  
indexing system. This was running on a dual dual core AMD 64bit system  
with 8G of RAM and we regularly saw load averages over 5 and all 8GB  
of memory used.

There are a number of good tuning pointers for larger installations  
and supposedly version 5.x is much better. I suspect that being from  
Comcast being in the middle of their implementation and providing  
feedback.
