| How can headers be forged? |
|
It's trivially easy to forge a "From:" or "Reply-To:" header, as most email programs allow users to specify these headers themselves. The ability to specify any "From:" header can be quite useful, enabling you to, for example, use our secure SMTP server to send mail with the From: address set to your home or work email address. Other headers that are harder to forge are the "Received:" headers. While these can be quite misleading as well, they are still normally quite useful in identifying the real source of an email message. |
