Just received a spam email seemingly sent with my Yahoo email address, so if you get one from my Yahoo address called 'January 74% off', it's not me, don't open, but my question is how do they do that? The email address is identical. How can they possibly pull that off? I've got a number of other emails, and it's about time I ditched Yahoo since it's so painstakingly slow and erratic, regardless of which Yahoo version or which computer I use, but can I prevent this from happening to other email addresses? I'd be grateful for any advice...


Kristine,
It's called spoofing and has nothing to do with Yahoo!
Check this out - scroll down to "Fabricated (or spoofed) IP addresses." This will give you a start to understanding...

From experience, be thankful it wasn't your personal domain being spoofed - that can cause enormous headaches!
Good luck,
Mark

Yes, if it is your @Yahoo address then it is not so much of a long-term problem. The issue can be if your personal domain name ends up getting black-listed because of the actions of these sharks.

Thanks guys. I had no idea that this could be done to email addresses, but vaguely familiar with the problem of personal domains being hijacked this way - that's part of why I've been reluctant to map my domain to my blog.

It's dead easy to do, and an unfortunate fact of life.
All they are doing is grabbing an existing email address and faking the reply to and sent from field.

I wondered about that too.
P.S. Hey ... just saw you in the Viking!

Really? That's cool. I haven't seen The Viking myself yet: as I'm stuck in the land of The Vikings I expect it's going to take some time to ship the magazine to me. Fortunately, the world's moved on from the time of the longboats, which must have taken God knows how long time to cross the Atlantic...
