Linda is frustrated that some of her contacts always end up in the spam filter. Leo says that somewhere the email program learned that those contacts were sending spam, and it may be due to the content of the email. Leo recommends setting up a separate filter that will keep those contacts in the inbox. They may also be called "rules."
Suzanne uses Hotmail and all of a sudden, she's getting hundreds of spam from subscribed newsletters. She also got an email about an order for a GoPro camera bought at Walmart. Leo suspects that someone doesn't like Suzanne or has stolen her identity. It's a new scam where hackers overwhelm your email address with bulk emails to distract you from the actual identity theft going on. It's called "Chaff." The idea is to be so overwhelmed with spam and bulk emails, you miss the stolen credit card activity. Shame on companies that allow signups without a double opt-in via email.
Vic is bombarded by email addresses that an email can't be delivered. Leo says that Vic's email has been "spoofed" by spammers and that they have been using his in the From address line. The bad news is that there's really nothing he can do about it. The good news is, it usually stops shortly as they move on to another email address to spoof. He can set up a filter to send those emails to the trash and never see them, though. He should use "Mailer Daemon" as the criteria. That's usually what sends the bounced spam message.
