php email form tut question!

[berkoWitZ]

hey, I have this problem, I did the tutorial here on kirupa about the php mail form and it´s working ok, the emails arrived to my email but if I write a wrong email the email still works, I want if anyone writes their email bad to not submit the email, that the form tells them, I hope I explain it ok, thanks!

I dont think there is a way to do that without sending them an email and them clicking a link in the email to a page that verifies it in the database and then allows them to send the email.

The only thing remotely like this that i'm aware of is checking the string to make sure it's a valid email (somethgin @ something dot com) by using the str functions. But it still doesnt ward off emails like fake@fake.com
