I know this has been asked before, but I can't seem to find an adequate answer. In both Lotus Notes and MS Outlook, one is prompted for a password on opening (not just mail synching) that prevents access to your downloaded emails. Apple Mail doesn't seem to allow that...the password synchs only to the POP server, thus making your local email readable to anyone. I've heard the point about users and accounts, but that creates even more headache for me. I've got a Mac Pro, which is my system, but also the primary "home media center" for the family household. So I want iTunes, movies, iPhoto, etc, always available. Setting up different "accounts" and users for everyone creates a nightmare to share and organize the "public" apps and files. I also don't want to "password" protect the account and system, as that still limits the access to "public" apps. And having a separate account for me, still means I have the headache of synching these "public apps" to my account. This would all be much simpler if I could have Mail require a password upon opening. I do still want my email private. I don't think this is such an extravagant use case...seems like a lot of folks are looking for something similar. It's the only thing I'm missing from Windows XP. So has anyone sorted a means of doing this?
