I'm using the open source version of Zimbra with Ubuntu and it's working very well from a lot of time.
Now I would like to switch the server on an MAC machine so I've made a fresh install of both operating system and zimbra 5.0 RC1.
After the fresh install I'm not able to set the relay MTA address for external mail delivery because the browser tell always that the value inserted isn't correct.
Anyway I can solve this by using the zmprov ms command.
The big problem is the server crash after any changes in the admin panel, for example if I try to disable some unnecessary process or the POP feature I loose everytime the web access!
After the save I cannot get the web login page anymore, it seems a webserver problem, but I can see the process running, I can reload, but the problem still persist: no more web access to the admin panel or to the wemail.
Maybe this is an already know problem, but any help will be appreciated.
