Yes, but if you dont, you always have the option to download a local copy of your mailbox. This is how I use email. I use fetchmail to deliver mail to a local mailbox on my hard drive. I don't delete it from the online mailbox, in case I want to access it from the web, but I have my local copy in case the online provider either goes away or does something else with it.
