Mail()'s not playing nicely :(

ok so i got mail("me@home.com", "$message", "sms alert", "Return-Path: $email <$email>\nFrom: $email <$email>\nReply-To: $email <$email>\nX-Mailer: " . phpversion()); the email appears as from root@myserver.com istead of me@home.com which it should (and always has done previousy) I looked at the headers and from reply-to and return path are all set ok but it sticks in another return path right at the top to root@myserver.com wtf is going on?/
