POP3 *is* based around downloading emails while IMAP is not, but all the POP3 programs I've used allow attachments to not be downloaded, or only emails below a certain size to be downloaded. Most of the POP3 programs I've used also allow emails to be kept on a server until explicitly deleted, which makes them work very much like an IMAP client. As a result, I don't see the point of IMAP at all... You're point might still be relevent though, because someone might not have their POP client setup to not download 10Mb files and therefore run into these sort of issues. Roberto/.
