[Evolution] Does Evolution retrieve email even when it is not being run??

[Evolution List]

I've noticed something the last few times I've closed evolution with no
new, unread emails present.  When I open it up again there's a bunch of
emails waiting for me to read as though I had never closed out
Evolution.  

Does Evolution continue to read emails, even when I close Evolution down
while doing other things on my desktop?  

I know that the calender reminder application continues to run but does
automatic email retrieval also continue to run?  If so, is there a way
for me to disable this?  I don't want to risk corruption of an email by
shutting down my computer while Evolution is trying to download one
(however remote the chance of it downloading while I am shutting down
is).  I reboot quite a bit these days since I am testing various
bootloader options and such.  

Thanks.
