O.T. email management ?

[Architect mike enriquez]

I have several email accounts and I need to find a way to manage them. I 
wonder if anyone in the plug community has come up with a good way to 
handle multiple accounts.
I can put them all on one computer, I can put each account on its own 
computer. Next what should they all be using the same email application 
and which one is the best for multiple accounts?
Does anyone have a good idea on this?
Thanks
