i just got a new white macbook (2.13ghz variety), and i was curious about mail. i would like to use mail on my macbook, but, i don't want it to store copies of my mails on my hard drive. my question is, if i set mail up to retrieve mails from my gmail account, does it store copies on my hard drive? i have a ton of mails, and i don't want them to clutter up my brand new macbook. thanks!
