I got GA version from CVS (with "co CRAY"), then build it, the rpm packages all are 162 release, and there's no Instant Messenger feature in it.
Follow the link http://prdownloads.sourceforge.net/z...6.tgz?download
, build it, the release is 156, with IM feature.
But if I get the binary version that zimbra offer (156 release), there's no IM feature also.
Maybe they're not sync. here.
