Next step in restoring my settings was to get the working rules and all the blogs into rss2email. I have subscribed to more than 150 blogs. So, adding all of them manually was difficult.
For a time like this, I subscribe to all the blogs using google reader and then add them to rss2email. So I had quickly exported the google feeds list and then had to find a way to extract the URLs for the blog to the rss2email.
