title: Procmail to automatically make new folders to store emails from new senders
body: <p>I am learning how to use procmail but at this point, I am not even sure it's the right tool for what I am trying to do. </p>
  
  <p>So far, I have managed to get fetchmail to retrieve emails from a Google IMAP account and procmail to filter those emails into local folders I had previously created. </p>
  
  <p>I am wondering though whether there is a way to get procmail to automatically create a new folder locally when an email from a new sender is being retrieved and to store that email into that folder. </p>
  
  <p>So far, I have only found a website that describes the possibility of procmail creating automatically folders for mailing lists, but the recipe is something crazy using characters which I have no idea the meaning of, furthermore the official procmail website seems unreachable. </p>
  
  <p>Please can you help? Thank you.</p>
