zefboxedl.com, registered on 2023-12-06, has a risk score of 24. With no DMARC or SPF policies and classified as a disposable email, its sender reputation is poor. The domain's undeliverable status, lack of MX records, and invalid SMTP further impact email deliverability, making it highly likely that messages will be filtered or rejected by recipient mail systems.

To improve domain reputation, zefboxedl.com should promptly implement DMARC with enforcement, verifying messages originate from authorized servers. Next, maintain a consistent sending volume, avoiding sudden spikes or suspicious patterns. Third, remove the disposable email configuration, ensuring legitimate user accounts. Finally, authenticate email traffic using DKIM and enforce strict SPF records, proving authenticity and deterring spoofing attempts. These measures will significantly improve trust and reduce spam filtering overall.
