Hello,
Today, while we are testing quarantine webmail feature in our labs, I got a mail marked as a certainly spam in my SurGATE quarantine mailbox.
The funny part is here, the spammer puts the full bash man page to bypass or poison Bayesian database in html div area like below.
But he could not delivery the spam to our mailbox. It was matched by our spam signature database based on url and some other unique patterns in the mail.
