Spoofing and Emails - From or Form

The monthly report from my Norton program suggested this link regarding email security, but has confused me. They have called this "Form spoofing" and I quote:

Form-spoofing is annoying, but it’s not dangerous. It’s the sender entering your name and address into the From field in their mail program instead of their own. Outlook, for one, makes this a snap. During the setup process, when asked to enter one’s own email address, spammers choose this option.

Since the name of the game for spammers is hiding their tracks and making sure you receive their mail, from-spoofing is natural. By putting your address in the From field, they obscure the true sender and nearly guarantee that your spam filter won’t block their email.

[end quoting]

I searched for both "Form spoofing" and "From spoofing" and I think this problem with email is best described as 'FROM-SPOOFING'.

This article on Email spoofing makes no mention of "Form spoofing", but does mention "from" and "Reply-to" (http://en.wikipedia.org/wiki/E-mail_spoofing).
