I got an email today from one of my old computer repair customers in Portland that told me I was sending out viruses, and wondering how I could be so careless.
I know darn well I’m innocent, but trying to explain that to people can be a pain in the neck. Now, when someone tells you that you sent them a virus or a phishing scam, you can just send them a link to this blog post.
Basixcally, what’s happening is that spammers are using anydomainname.com to send out their mail messages. when someone goes to reply, it looks to the user like it came from you.
However, if they were to view the headers of the email, they would see that is really came from elsewhere.
For a more technical explanation of “spoofing” read this, but you can likely take comfort in knowing that you’re not sending out spam. Unless of course, there’s spyware on your computer?
