How could that be possible?

[Blaze The Movie Fan]

Some spammers spams my e-mail by using my e-mail address as the sender, how could that be possible? I'm confused? How could that be possible? Someone?

[JelZe GoldRabbit]

My guess would be that they "masked" their email address with your own (yes, it's possible, I even have a program that does that sorta thing, called "Annoymail"). Yes, that's easy to do, it just takes a little tweaking in "Sender information" :)

Check the originating IP address and you'll find it's not coming from your email provider either.

Dead easy - you just set whatever you like for the To and From headers. It's what most spammers and all the recent email viruses do to a) avoid detection and b) fool you into thinking a friend sent it.

you can easily get their IPs and report them to webmasters or something

Does that means, Microsoft INC. weren't behind all this? Were some spammer were sending as Microsoft and send me virus? Well, my computer is safed thanks to Yahoo!Mail which has powerful VirusScan!

Indeed, they were just pretending to be Microsoft.

I don't think Bill Gates or his company would send viruses!

And that is exactly why viruses spread by pretending to be from reputable companies like Microsoft.

Any reputable company will not send unsolicted e-mails, and never with attachements. If you get an e-mail with an attachement that claims to come from someone like Microsoft or Symantec (and that you weren't expecting), then it's usually a fake designed to get you to run whatever virus is contained in the e-mail.

Well, I can't download viruses anyways, and http://yousendit.com doesn't allow you to send virus anyways!

There are websites that allow you to send emails under any sender name you want. So yeah, its possible and I'd think common too.

Just find an open mail relay, and go use that. Or if you're feeling fancy canabalise one of the many spam-bots and make it run under your control.

Most viruses are designed to trick microsoft outlook users, where there is no built in attachment scanner of any kind.
