Exim to Zimbra Migration
I am a system admin here in my firm where we have mail server hosted by 3rd Party.The Exim Mail Server is running on Linux Machine.I can see cPanel which shows me information of mail accounts.All I need is to migrate it to Zimbra MAil Server(Open source version). There are 200+ mail accounts all over.Anyone who can suggest where to start or any guide which I can refer to.
Do I need to use cPanel to export it into csv file? If not, what command do i need to use for the same?
