Posterous

To import your posts from Posterous, run:

$ ruby -rubygems -e 'require "jekyll-import";
JekyllImport::Importers::Posterous.run({
"email" => "myemail",
"password" => "mypassword",
"api_token" => "mytoken"
})'

All three fields are required.

There is also an alternative Posterous migrator that maintains permalinks and attempts to import images too.
