Two findings block deliverability.
vinterro.digital has no enforceable DMARC policy, so mail that forges its domain is not blocked at the recipient.
Your domain does not have an SPF record published in DNS. SPF helps mail servers check whether messages sent from your domain are coming from approved senders, which can reduce spoofing and improve deliverability. To fix this, add an SPF record for the domain that lists the mail services you use to send email.
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.

v=DMARC1; p=none; np=rejectYour domain registration is due to expire in 10 days, and the TLS certificate will expire shortly after that. If either one lapses, visitors may see your site stop working or warning messages in their browser. Renew the domain and replace the certificate before the expiry dates to keep the site and secure connections available.
