Full headers follow, but it seems the shopify detection in the above
isn't quite correct;
Return-path:
<bounces+11006833-f9b2-vmstfpodc=mattcorallo....@mailer.shopifyemail.com>
Envelope-to: vmstfp...@mattcorallo.com
Delivery-date: Mon, 15 Nov 2021 21:10:55 +0000
Received: from o13.mailer.shopify.com ([149.72.221.62])
by mail.as397444.net with esmtps TLS1.3 id 1mmjFb-0034Ki-02
(envelope-from

for vmstfp...@mattcorallo.com; Mon, 15 Nov 2021 21:10:54 +0000
The lack of any name inside the parentheses before the bracketed IP in
that Received header implies that mail.as397444.net could not get a
verifiable rDNS name for that relay.
In short, SA trusts your MTA's indication that this may not really be a
shopify relay.
Even shorter: It's DNS. It's ALWAYS DNS.

0.8 RDNS_NONE Delivered to internal network by a host
with no rDNS
2.0 HTML_FONT_TINY_NORDNS Font too small to read, no rDNS
2.5 SHOPIFY_IMG_NOT_RCVD_SFY Shopify hosted image but message not
from Shopify
0.0 NORDNS_LOW_CONTRAST No rDNS + hidden text
X-Spam-Score: 6.3
That's 5.3 out of 6.3 caused by the inability of mail.as397444.net to
get a verifiable rDNS name for 149.72.221.62 at delivery time.
It's ALWAYS DNS.
