I am using css tricks simple email form. I have it where it does send email to the email address I specify. However, when I reply to the email I am getting emails that are not able to be delivered. I know that some people enter false email addresses. What is a simply way to check to make sure I have not messed up the php. This is the first php I have used. Yours Truly, Texas Pete
