Subject: [Declude.JunkMail] VIAGRA won't die

Apparently, this means "Generic Viagra" as revealed in the Declude Log file:

 

 =?iso-8859-1?B?R2VuZXJpYyBWaWFncmE=?=

 

What can you do about obfuscated subjects using ISO character sets? I was thinking of filtering them based on partial string, like this:

 

SUBJECT 30 CONTAINS =?iso-8859

 

Is it safe to filter this? In other words, would a legitimate or casual sender ever use such a method to display a subject? Is there a list of ISO charcter sets that can be filtered?

 

Thanks!
