Hello! When i try to use outside account by imap, i have the next log:

INFO [btpool0-8] [name=selffik@qwerty.ua;mid=4;ip=192.168.0.186;ua=Z imbraWebClient - FF3.0 (Win)/5.0.9_GA_2533.F7;] datasource - Test failed: javax.mail.AuthenticationFailedException: Server certificate not installed

How to install Server certificate, its depend of zimbra-server or imap. I used imap-uw, thanx in advance.
