[CentOS] Kerio Mailserver on Centos 5

I was wondering if any of the mail admins on here have used the kerio  
mail server on centos, and their thoughts on it.


My initial testing is going very well - but was hoping for some  
unbiased opinions (as opposed to asking on the kerio forum) on it's  
use with centos (5 in particular if possible). THE typical q's - IE  
performance, issues, etc.

Thanks in advance.
