Php Coders help needed

[acctman]

i need help with a form mailer php script. i downloaded a free php form mailer script works well but i when mail is received the sender is "Nobody". My question is, is it possible to have a form script in which the user inputs his/her email address and its sent as the From?

i need it to work this way so my dog Sony Aibo ERS-7 can resend a reply back to users email address in the From field. i tried something like this, but it didn't work.

mail("[email protected]","AIBO MAIL",$msg,.$HTTP_POST_VARS["email"].);

mail("[email protected]","AIBO MAIL",$msg,"From: " . $HTTP_POST_VARS["email"]);
