At least for me, the Next Big Thing™ in email spam is for the spammers to use my own email address, spoofed, as the sender, and then put some gibberish, not real email in the recipient field, so that I get the "Delivery Status Notification (Failed)" email. So, for the past month or two now, I've been getting multiple daily emails from mailer-daemon@googlemail.com telling me that the email "I" tried to send has failed to go through, such that I see whatever bullshit spam email they wanted me to see. Or at least that was how it was at first, before I just set up a filter to auto-delete emails from mailer-daemon@googlemail.com. Granted, this now means that I won't know if I legitimately try to send an email to someone and, like, get the email wrong or something such that it bounces back, but I think I can live with that. I almost never send emails anymore, anyway, except to family, whose contacts are already in my address book thing.
This basically.
