Is there a way to get my Entourage to automatically compress mail attachments to .zip files instead of .sit files. No one (PC users, a.k.a. "everyone") can open .sit files unless they download some expensive program. I know Stuffit will do Drop .zip, but its a hassle to do that every time you want to send a group of pictures or something. The entourage prefs has only stuffit or none to choose from.
