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. For Gmail, he should click on the gear and then settings. Select filters. He can add it there.
