||Using IMAP on Mac OS X|
Response to: Storage limits
Well this is an interesting point you point out.
I have been thinking from the perspective that IMAP will be set on a company own mail server.
But for the case of ISPs or hosting environment (e.g. Unversity mail account), I agree you are right: one can effectively 'store' more message with POP without violating the limit. This couples well with the fact that most ISP only offer POP.
