What is Anti-Spoofing Technology

[DVD_Ripper]

We are testing a new web based e-mailing tool that of course is not part of our corporate domain -- subsequently when we sent some tests to our email addresses yesterday our mail server bounced it because we said the email was coming from our corporate domain (and it wasn't)

The vendor said it could be due to "anti-spoofing" ... what is that?

Hello,

Well spoofing is making a fake something. I guess the anit of that is weeding out the fake stuff???

---now mpaa and others are putting out fake movies to clog up p2p and that's called spoofing, when they find out the fakes they put out alerts to avoid it, so I guess thats anti spoofing - this was on 60 minutes the other week - I'm not condoning or supporting file sharing of illegal movies -DON'T DO IT!!!---

Spoof is the sound you make when you have a case of intestinal distress and have a case of the high pressure Squirts !!

The little I know: It's refferring to the header on the e-mail. The e-mail sender is ID'd by the header in the e-mail. If you change the header to say it's coming from site A when it's really coming from site B your spoofing the origin of the e-mail. Spammers use this to try to hide, in other words the mail server thinks it's spam.

Anti-spoofing technology basically makes sure that emails (and other communications) are really coming from where they say they're coming from, as opposed to being either redirected or 'faked' to look like they're coming from somewhere they're not.

Years ago (and I think to an extent it can still be done) you could send an email from Outlook Express through your hotmail account using your own personal username and password, but having the email show up with someone else's username and password. It helped if you had email from them so you knew exactly what their mail name showed up as. I got more than a few laughs out of that back in the old days. :P

-------------------------

EDIT: sorry, not their password, just showed their email addy and their email nickname just like theirs.

Great... thanks, I will check with our propeller heads down in our SMTP server room to help me figure it out now that I've got an idea on how it functions.

If you are running a server, you can get something like Persits Mailsender to generate and send mail via asp code. you can have a blank from name and email addy so that the only thing to trace it back to you is your exchange server's IP. It would truly appear as a "ghost" email - we scared the living suitcase out of quite a few people at work with it. With relaying being more prominent, if you could find out the IP address of a public exchange server, it would be untraceable.

To spoof or engage in spoofing is to send up or make fun
of something. For example, the Naked Gun movie series was
a spoof of various "cop buddy" and crime movies.

Now on the net, spoofing refers to id theft. You can spoof mail headers,
web url's, proxies, internal and public servers. Many warez sites
are spoofed on Yahoo's web domain, for example. Basically you can
take an email or any internet id reference and make it appear to
have come from someone else.
