A long time ago, I was a die hard Outlook Express user (remember Outlook Express?). By default I graduated (if you want to call it that) to Entourage. I'm glad to say that now I am sending/receiving 100% of my email messages via Mail. There are many things I like about it, including the fantastic junk mail filter, the integration with iPhoto (in Tiger), the iChat status of my online contacts and the smart folders. Plus, since I'm primarily using a .Mac email address, it practically sets itself up for me. All of this is great, but what really intrigues me are those smart folders.
I have several email accounts. I like to set up rules and custom folders for the sake of sorting these messages when they come in. Instead of wading my way through a mess of messages in the general in box, I create a folder for each account. So mail from Account A goes into the Account A folder, and so on. Also, some messages get further sorted. For example, messages alerting me to comments posted at my personal site are sent to a folder all their own. The whole purpose is, like I said, for the sake of organization and readability. Read more after the jump.
