UPDATE: ADDED A DMARC Record based on microsofts doc here:Send feedback to Microsoft. More Info for Email Admins Status code: 550 5.7.363 It appears that the recipient's email server at thecaswells.net performed a reverse DNS (rDNS) lookup security check to verify that the IP address the message is coming from is associated with the sending domain, and the lookup failed. It appears that the pointer (PTR) record for dryheatembroidery.com isn't set up correctly. Set up or fix your domain's PTR record - If you're the admin for dryheatembroidery.com, work with your DNS hosting provider (your domain registrar, Web hosting provider, or ISP) to correctly set up a PTR record for your domain. If you're using Office 365 to manage your DNS records note that PTR record creation and management isn't supported in Office 365, so you'll have to change your DNS management to a DNS host outside Office 365. Refer to this article for more information and instructions:
