# IMAP on a diet - Speaking of large files, heres another great feature of IMAP. You can configure your IMAP client to only download what it needs to. On my palm, for example, its configured to only download the first 5000bytes of every message. Thats enough to get the text of all but the longest rants, and plenty enough to know whether Im going to delete the email, forward it, file it in a folder, or wait until Im back at a real keyboard to respond. Same thing with any attachments. I can download them if I want, but by default, they stay on the server. I can still delete the message, move it to a folder, all without actually getting the entire message on my palm. This saves tremendously load on the network, on the device, and just plain makes sense.
