Suggestion: email anti-spoof measure on web site

[ma.huijuan () gmail com]

We often find web pages with the feature to freely (without authentication) send emails to anybody you specify. For 
organsizations who have implemented anti-spoof measures on email servers, this opens up a loophole for spammers to send 
spoofed emails. 

Suggestion: For organizations who are concerned about spoofed email, the feature of sending emails without 
authentication should be removed on all their web sites.

I believe this should also be included in OWASP guide. 

Anybody has any objection on this suggestion? Do let me know, thanks.
