I have been noting an big increase in spam that contains html and images One common feature is that these emails contain hidden text that only shows up when I look at the source
I found samples of this at http://www.hoax-slayer.com/hidden-text-spam.html Right now I have been having some success by blocking a country , in the most common instance .eu, in the header checks but can’t think of a body check to catch this when it spread further I would appreciate any suggestions
