I'm planning on switch away from my custom home-brew email solution to Zimbra when 5.0 is released. I'm very impressed with the work you all have done!
In testing 5.0 rc1, I noticed that the popups for "tomorrow" and date keywords and such when displaying email messages does not appear to be functioning. Is this a known issue or is it a deprecated feature or am I just missing something? I've tested with Firefox and Internet Explorer.
BTW, I'm highly pleased with detection of Safari and automatically defaulting to the basic client. =)
Again, great job y'all!
