I've been using the mentioned MailScanner software in the past as well. It 
also has a feature to block/mark duplicate extensions which are typical 
for phishing spam, for instance "something.pdf.iso". Note: this will 
detect *any* combination, not just "pdf.iso".

Looking at the documentation I was wondering if I could achieve this with
a filename map that uses
I can create a regexp for that, for instance
but this wouldn't work as it wants to extract and compare against a map.

Is there currently a way to achieve such a generic test?
