Well a simple reply "it will do all you need" is not adequate. Answer is Yes and NO. If your a simple home user - not connecting to corporate enterprise email as most users are, then dont use ZD 2.0. Use the older version 1.04 - much simpler. ZD 2.0 is meant to connect to an enterprise server. If your just using your own simple POP accounts ZD 2.0 will complicate things and not work as easy as the prior version. Trust me, I am like you and use just pop accounts and ZD 1.04 is the way to go. It won't be updated but it simply works ok. ZD 2.0 i tried to use as standalone email and it was a nightmare. Hope it helps!
Get the old 1.04 when it was by Yahoo

If you try to use ZD 2.0 in a non enterprise environment as most home users wish to do, you will pull your hair out!
