moBlog
moBlog is a little email to weblog gateway. The nifty part of it is that it can handle attachments which allows you to post files, especially images to your weblog. This makes a posting pictures from your camera equipped Cellular/Mobile/Handy/PDA extremly easy.
moBlog uses xml-rpc to upload pictures. Currently it needs a patched version of antville to work.
moBlog runs on its own account checking ~/Maildir for regulary for new messages. If it finds one it parses the MIME structure looks up the sender and recipient address in a config file to find out which weblog to post to, then upload attachments and finally generate a new posting referencing the uploaded images.
