To check if zfymail.com has been flagged by spam filters, we need to see if the domain or its IP address is listed on common DNS-based blacklists, run diagnostics on SPF, DKIM, and DMARC, and review sender reputation metrics. Use Abstract API's IP Abuse Check tool to get a complete report on abuse, blacklists, and suspicious activity for zfymail.com.

With a registration date of 2017-06-05 and a risk score of 34, zfymail.com has a moderate email sender reputation. The lack of DMARC enforcement and no strict SPF policy weaken its trust signals. Despite being deliverable, the domain's disposable email classification and moderate risk level can impact inbox placement, making emails more likely to be filtered or rejected.

To improve domain reputation, zfymail.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, proving authenticity and deterring spoofing attempts. These measures will significantly improve trust and reduce spam filtering overall.
