rss2maildir
rss2maildir is a simple python script that takes rss feeds and creates maildir messages for them, when an item is changed, the new content is added as a thread item to the previous mail so that changes can be easily seen.
The code for my version is in my git repository, it appears that in the time since actually releasing that code in to the world, at least 2 different forks have taken place, I haven't investigated far enough to see what the big changes are, but it appears that mostly they refactor the code in to smaller, more manageable pieces.
To clone use either of:
git clone git://git.sommitrealweird.co.uk/rss2maildir.git git clone http://git.sommitrealweird.co.uk/rss2maildir.git
