    I’m using your plugin with Google mailer settings. I want to send a custom message ID through google mailer. How I can override that?

  • Hi @koushikcodesigma,

    Currently, there’s no built-in option for that. If you’d to, this can be accomplished with a little custom code: 

    add_filter('wp_mail_smtp_custom_options', function( $phpmailer ) {
    $phpmailer->MessageID = '';
    return $phpmailer;
} );

    Please note that the message ID must be in the format “<id@domain>”, as defined in RFC5322 section 3.6.4 or it will be ignored. See https://tools.ietf.org/html/rfc5322#section-3.6.4

    In case it helps, here’s a tutorial on how to easily add custom codes in your site.

    I hope this helps!
