Couldn't wait to install the GA version of 5.0. Very nice job. All the things that didn't use to work for me are now fixed, even the recalcitrant logger problem (statistics not displaying or active services not shown). I can also now access my documents and briefcases via my proxy configuration (http://xxx.com/zimbra -> http://xxx.com:8080).
Not sure why there was no sensitivity to the usual updates to the logger restart (killall ->syslog restart) for OpenSuse and some of the spam customization had to be partly redone (as always) but that was a 5 minute job and I was prepared for it.
Thumbs up. Happy camper here.
