For the longest time, my wife and I have been using Eudora as our mail program on our succession of Macs. As many of you probably know, you can configure your Mac in such a way so that by double-clicking on the Eudora Settings file, you will launch Eudora pointing to separate mail files. From the perspective of the user, they have their own personal version of Eudora on a computer that is configured with only one user account. What I would like to do is have a similar configuration for Mac Mail since Eudora is starting to get dated and go flaky on me with Leopard. Is there a way to setup Mac Mail so that depending on which icon you click on, it will launch either mail for me or mail for my spouse? Right now all I can figure out is that I can have a single mail application that will allow me to pull up both accounts. I don't really want that - I would prefer to have one computer log-in with two (apparently) separate mail environments. Any suggestions? Thanks!
