[Evolution] Leave messages on server

[Jeremy King <jeremy jeremyking com>]

Hello everyone! i'm new to evolution (2.8.1) and as i was setting it up,
i did not notice an option to "Leave messages on server"...is that
available? i use webmail so that i can check my email wherever, but at
home i'll probably use evolution - thus i don't wanna delete messages
from the server...

thanks
