Need help with post via mail web 2.0 properties

Hi,
I'm developing article creator and poster (via mail and via RSS).

I can't find list with good sites that have post by mail feature.
For now in my list for post via mail are:
- wordpress (and wordpress sites)
- blogger (and blogger sites)
- tumblr
- evernote
- postagon

Please, give me idea! I need sites that can post via mail on them. Will be tankful if you also suggest web 2.0 properties, that can import posts via RSS (weebly like). These sites must be free to join and post.
Thanks in advice!
