I am trying to get the email to sms gateway to work for home automation notices. I can send to MyMobileNumber@tmomail.net via my work account, but not my personal email account. My personal account is on a domain owned by me (danfield.net) and has correct settings for SPF, DMARC, etc. I have read all postings here related to this error and can't not find any solution.
This is the mail system at host gateway7.unifiedlayer.com.
