But it seems like the 'From:' address being given to the PHP mail() function is maybe being ignored, because the error log lists 'www-data@homemade' as being the sender, rather than listing the shaw address. The snippet from the PHP code: $email = $_POST['email']; ... mail($to, $subject, $msg, 'From:' . $email); I have tried setting both $to and $email to be the same shaw address since I assumed it should be recognized by the mail server, but it's still getting bounced. So why is 'www-data@homemade' being listed as the sender? Any ideas?
