The variables extension is what you need. Here's an example:


require ["variables", "envelope", "fileinto", "subaddress"];

if envelope :is :user "to" "sales" {
     if envelope :matches :detail "to" "*" {
         /* Save name in ${name} in all lowercase except for the first 
letter.
          * Joe, joe, jOe thus all become 'Joe'.
          */
         set :lower :upperfirst "name" "${1}";
     }

     if string :is "${name}" "" {
         /* Default case if no detail is specified */
         fileinto "sales";
     } else {
         /* For sales+joe@ this will become users/Joe */
         fileinto "users/${name}";
     }
}
