What is the Purpose for the Random Stuff in Spam?
I received some "generic Viagra" spam in my e-mail box, and happened to notice the following text at the end of the spam:

flu from neighbouring countries and regions And so here they are once again The new prime ministers credibility is on the line if he backs down on a promise A SUICIDE driver detonated a massive car bomb one win away from reaching the Super Bowl whose once faltering campaign for nomination has rebounded

If this spammer is a budding lyricist, s/he has a long way to go before s/he can produce a "Binky the Doormat."

I also can't understand the random letters that appear at the end of spam message titles. Am I correct in assuming that's a tracking mechanism?
