One thing I liked about the new Mail.app in Leopard was the ability to aggregate not only my email, but RSS feeds right into my inbox, so I could just scroll through and read all my feeds in line with my email.
Well, Mutt doesn't do it natively, and I couldn't find a patch in the 10 seconds I was Googling to perform this action. However, I did find a nice tool called "rss2email". A program written in python that takes the rss feeds that you give it, reads them, parses them into either plaintext or html, and then sends them to you via whatever smtp server you want.
It works great and I highly recommend it. All you have to do to automate it is to cron it. Done.
