No big deal

Although it's defintely worth mentioning, as it does impact managed anti-spam services pretty badly, as far as the average geeky user is concerned, that's not a big deal. The number of times I receive a mail from a valid sender with a PDF/GIF attached is probably counted on the fingers of both hands, per year !

Thus thunderbird has learnt the trick after 3-4 times of that crap ...

Looking forward to the next spammer trick ...
