One finding blocks deliverability.
medrano.net publishes an enforcing DMARC policy, so mail that forges its domain is quarantined or rejected at the recipient.
Your website’s TLS certificate has expired, which means browsers may warn visitors that the site is not secure. This can break trust, cause checkout or login issues, and hurt traffic. The fix is to renew or replace the certificate on your web server before it expires, and make sure it stays set to renew automatically in the future.
domain registration expires 2026-12-01; TLS certificate Your SPF check is currently set to a softer mode, which means mail from senders not on the approved list is marked as suspicious but is not fully blocked. This usually still works with DMARC, but it is a little less strict and can let more unauthorized mail appear to come from your domain. If you want to harden it, change the policy to the stricter “fail” mode only after you are sure every legitimate sender is included, so you do not block valid email by accident.
