hey everyone i am using formmail to send myself an e-mail containing all of the information about someone trying to cancel a service to my site. i was wondering if it would be possible to, before sending all of the information to formmail.php's built in functions to pass the information through my own that i have written that does things such as make sure e-mail domain's really exits as well as just text fields containing only numbers or letters instead of just being blank?
thanks and any help is appreciated
