The domain sirenic.eu publishes no DMARC record. DMARC is what tells receiving mail servers to reject or quarantine messages that fail your SPF/DKIM checks. Without it, an attacker can send phishing emails with a "From:" address at your domain and inboxes have no signal to distrust them — a favourite trick for invoice fraud and credential phishing.
sirenic.eu publishes no CAA records. CAA tells the world which certificate authorities are allowed to issue HTTPS certificates for your domain. Without it, any CA can be persuaded to issue a cert for your domain, which widens the door to mis-issuance.
