Nope. Because the destination is not taken from the form. Only a key to a list
of predefined destinations is in the script.
For instance - they could say "destination=1" which might send to customer
service. But they could not say "destination=youvegotspam@example.com" because
that will not be found.

Cookies can be falsified, and it doesn't take a lot of looking to figure out
what you use in a cookie. Additionally, this method doesn't work if the client
has cookies turned off.
Depending on cookies is NOT secure - and can be aggravating to valid users.
