I use zimbra 7.2. When I added another email account everything was correct. When I however wrote a message from my newly added account the sent email appeared in the Sent items of the primary account.
Is it possible to configure email accounts so that they behave separatelly? Eg. when I click on my newly added acount I would write a message with the identification of this account not the primary. Sent messages would go to the account which I would write from. Now everything goes to my primary accounts except received messages.
