[Discuss] Brilliant testing site for DMARC, DKIM, and SPF records

[Daniel Barrett]

I jut came across a fantastic site for testing SPF, DKIM, and DMARC
records for email delivery:

  https://www.learndmarc.com/

Simply send an email to this site, and it walks you through the entire
sender validation process. It's exactly what I needed to observe &
diagnose an email delivery issue. Hope this helps someone else.
