I have installed at my home zcs 5 on a debian 4.0 virtual machine.
zcs works perfectly but can't get external pop3 accounts automatically I have activated the automatic download of every pop3 account and every time i go to the pop3 settings the system reset the inbox folder of every pop3 account.

I have installed zimbra 3 times, deleting the entire virtual machine (because it's only a test for now).
Tonight i test another linux distributions in order to see if these problems are solved.

Anyone has these type of error?
