I've been using Qualcomm Eudora to handle my email accounts. While it's no longer being sold, it still works fine and I very much like the fact that it stores email messages in text format (some variant of .mbox), allows you to specify a separate directory for attachments to email (which are stored as files and not in a database) and has a very fast find feature. I also like it's message handling rules better than Microsoft Outlook.
At some point, I'm sure it will cease to work, but it's not having any problems and it works fine for me now, so I am continuing to use it.
