DKIM Signature brakes with HTML (multipart/alternative)

These are 2 emails sent FROM Woocommerce with PHPMailer 5.2.14 VIA Zoho's smtp TO Gmail.

One is sent as multipart/alternative

SMTPS id 1472887925932653.1288036547104; Sat, 3 Sep 2016 00:32:05 -0700

Message-ID: 2794079fbfa406a809a82a690ab1f488

One is sent as text/html

SMTPS id 147289704238276.96960297971964; Sat, 3 Sep 2016 03:04:02 -0700

Message-ID: 11b0666e538f89fb1fb1a757a91292ec

The only difference between these mails are the Content Type and the html in the body of the second one.

The one sent as multipart/alternative gets a verified DKIM signature, but the one sent as text/html does NOT, by Google ( body hash did not verify).

So Zoho is doing something to the html email after it has signed it? I would like to know what and why. Either I have to fix something or you need to do it at your end. As far as I can see it you use c=relaxed/relaxed in your signature, isn't that suppose to deal with this?

Tip of the week 15 - Add subscription-preferences option. Drive more engagement.
If crafting content for emails, getting creatives done, and running email campaigns is your love, then unsubscribes are the heartbreakers. You can save your emails from being unsubscribed/trashed by adding a proper subscription-preferences option in your emails (works best at the time of signup). Giving subscribers the option to choose what they want to receive from you and decide how often (frequency of the emails) your emails should hit their inboxes will increase the reach of your campaigns manifolds.
