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. The command to add a url is r2e add, so I wrote this one line just now to do the task for me.
Hope it helps someone:
Now all I needed to do was to setup procmail again to deliver the messages to my homedir. I already have posted article on procmailrc so that was simple. So all done. Hope this helps someone.
