One finding blocks deliverability.
trystencil.org has no enforceable DMARC policy, so mail that forges its domain is not blocked at the recipient.
Your domain does not have a DMARC policy set up, which means receiving mail servers have no clear instructions for what to do with messages that claim to come from your domain. This matters because it makes your domain easier to impersonate in phishing and spoofing attacks, and it also reduces your control and visibility over email delivery. The fix is to publish a DMARC record in your DNS for the domain.

Your SPF setting is using a “soft fail” ending, which means mail from servers not on the approved list is treated as suspicious but not fully blocked. This is usually fine for DMARC, but it is a little less strict and can let some unwanted mail through. If you want to tighten it, change the ending to a hard fail only after you are sure every legitimate sender is already included.
