I have two domains, called them example1.com and example2.com

on example1.com all emails sent with dkim sign.
on example2.com emails from php sent without dkim sign, but if send email from console, email will be signed.

ex. console command:

php -r 'mail("myemail@yandex.ru", "TEST", "TEST TEXT", "MIME-Version:
1.0\r\nContent-type: text/html; charset=\"utf-8\"\r\nFrom: no-reply <admin@example2.com>\r\n");'

test.php

<?php
$headers= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=\"utf-8\"\r\n";
$headers .= "From: no-reply <admin@example2.com>\r\n";
if (mail('myemail@yandex.ru', 'TEST', 'TEST', $headers)){
    echo 'OK';
}
else {
    echo 'FAIL';
}

This config need just for send emails, for receive emails I use pdd.yandex.ru
Where is problem with example2.com?

You may need to specify a "From:" header in the sendmail command. Opendkim only signs Mails with an aligned "From:" header.

  • I added test.php, there header From is exists., but on example2.com sending without dkim sign, if it was sent from php, but from console it sending with dkim sign. – Waki May 13 '16 at 12:39
