I have used Eudora off and on for years, with stints of using Mail and PowerMail in between, and so far Eudora just works while the other programs have integral problems that the developers either won't admit to or won't address otherwise. I haven't used Mulberry, mainly because it is even more of a visual nightmare in terms of its user interface than Eudora...
