Spam with the bodytext in a image

[Tobias Axelsson]

Hi
 
We have some problem with spam that sends a mail only containing a gif-image with the text in.
Offcourse they change the filename everytime.
 
I'm not sure if it's ok to attach files to this list, so I don't :)
 
One solution could be a md5sum-blacklist on attachment, becourse the md5sum does'nt change if you change the filename...
 
Is there current a function that I can use for this or is this maybe a future reliase feature to add?
 
Thanks for a great bundled software
