I am long due to switch from POP3 to IMAP but I am not sure how to go about it. I like to have a permanent copy on my Mac and at the same time get rid of the mail on the server every 6-12 months, depending on the size of my mailbox, while still being able to have/view the mail from before on my Mac. How would be the best way to go about that? Does anyone have it set up this way and has some tips? Thanks.
