`Spam' folder creation for multiple users

[Marek Kozlowski]

:-)

I've just added pigeonhole and a simple sieve script:
-------------------------------------------------
require "fileinto";
if header :contains "X-Spam-Flag" "YES" {
   fileinto "Spam";
}
-------------------------------------------------

If a user has this folder (`Spam') it works fine. If they haven't it 
results in an error.

1. Can I modify the script to create this folder if the need arise?
2. If not - what's the most recommended way of adding this folder for 
all users (~1000)?

Thanks!
Best regards,
Marek
