Which brings us back round to:

The only way to guarantee that an email address is actually going to the 
entity that entered it on your form is to send a verification code to the 
email address.

And even then, I suspect that there are some smart spamming systems out 
there that have email addresses and use eg curl to process the email 
verification links (which is why I use entity and not person above).
