the problem with non members is that some server in the path may discard 
or bounce our mail, and they won't get it.

why not use a header specific to the list instead of your address? I 
mean something like:

if header :contains "List-Id" "<gimp-developer.lists.XCF.Berkeley.EDU>" {
         fileinto "Mailinglisten.gimp-devel";
         stop;
}

This is independent on your address. so if you ever change the 
subscribed address, you won't need to change the rule. and if other 
users on your system need a similar processing, they can copy the rule.
