  • HI @lookya23,

    Thanks for reaching out. You can use the following custom codes and here’s how to easily add custom codes in your site.

    add_filter( 'wp_mail_smtp_custom_options', function( $phpmailer ) {
	$phpmailer->DKIM_domain = 'mydomain.ch';
	$phpmailer->DKIM_selector = 's1';
	$phpmailer->DKIM_private = '/home/clients/mix_numbers_and_letters/mydomain.ch/s1.mydomain.ch.pem';
	$phpmailer->DKIM_passphrase = '';
	$phpmailer->DKIM_identity = '[email protected]';
	return $phpmailer;
} );

    I hope this helps!

    HI !

    thank for your reply,

    i have put this inside my template fonction.php 

    add_filter( 'wp_mail_smtp_custom_options', function( $phpmailer ) {
	$phpmailer->DKIM_domain = 'MON-DOMAINE.fr';
	$phpmailer->DKIM_selector = 'k1';
	$phpmailer->DKIM_private = '/wp-admin/user/k1.MON-DOMAINE.fr.pem';
	$phpmailer->DKIM_passphrase = '';
	$phpmailer->DKIM_identity = '[email protected]';
	return $phpmailer;
} );

    1/ when you see ” MON-DOMAINE ” is for privacy, of course normally is my real name domain

    2/ K1 is good selector, i have make a record TXT DNS with this selector k1._domainkey.MON-DOMAINE.fr : v=DKIM1;t=s;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCvlJ6jGVLBb2fiq03vmmKx8Nk/YSP4rzwl9vgiHEGj5xiEWErwCd6TSmr3QgrpR4h/vYGk2tVElzLNCEvJHYiAqeXsM+il0lgXI1Z0Z/av33XzKMejGYY0yzEHCWVWoq1JsZf89bNDV2clMHWDDM3wOYsk2gPXMvhIyoOOIT+Z+wIDAQAB

    3/ ” /wp-admin/user/k1.MON-DOMAINE.fr.pem ” i dont know where pu this .pem file, i have put in this path … this file ” k1.MON-DOMAINE.fr.pem ” have the DKIM private key inside.

    4/ DKIM passphrase i don’t know what is it i leave blank space in this setting ..

    After that, When i check this setup with” DKIM Record Checker ” all looks good, this test don’t show any error.

    But ! When i send a test email with your plugin at a tools for analyse the email header for exemple (www.appmaildev.com/en/dkim) i get this feedback :

    DKIM-Result: none (no signature)

    Hi @lookya23,

    here is the official PHPMailer example with DKIM signing: https://github.com/PHPMailer/PHPMailer/blob/master/examples/DKIM_sign.phps#L23-L38

    The highlighted lines are the ones that you have to configure. I think your path to the pem file should be the absolute path to the pem file on your server.

    Also, use the password for the pem file (if you used a password protected pem file) -> DKIM_passphrase.

    I think once you correctly setup all DKIM parameters, it should work OK.

    Take care!
