The from address is not enforced. This can cause some PHP formmail script emails to be treated as spam. Fix:
1) add a -f(sender address) parameter:
mail($to, $subject, $message, $headers, ‘-fsomeone@somewhere.com’);
2) add a Return-Path header:
mail($to, $subject, $message, ‘Return-Path:
someone@somewhere.com\r\nFrom: someone@somewhere.com’);
Qmail is *meant* to check for the from address field in Sender, From, Reply-To, Return-Path, Return-Receipt-To, Errors-To, Resent-Sender etc.
etc. *but* only Return-Path will actually set the address.
i.e
<?
$headers = “From: \”mydomain.com\” <webmaster@mydomain.com>\r\n” .
“Return-Path: <webmaster@mydomain.com>\r\n” .
“X-Mailer: PHP/” . phpversion();
mail(‘support@testy.com’,’test’,’test email from mydomain.com’, $headers,’-fwebmaster@mydomain.com’);
?>
