Pop quiz time, gang. I hope you've been taking notes. Cause I haven't been covering this. In any event, how can I get an undeliverable email for an account through which I have never, ever sent an email with? The latest dirty trick in the spam wars? YES, I think it is. Congradulations spammers, you've managed to make me hate you guys just *that* much more, which I previously would've guessed was impossible.
