Implementation Tips

Start with Monitoring

Your policy is set to 'none'. This allows you to monitor without rejecting emails. After confirming all legitimate senders pass, consider upgrading to 'quarantine' or 'reject'.

Add Aggregate Reports

Aggregate reports provide daily summaries of authentication results. Highly recommended for monitoring DMARC effectiveness.

Consider Strict Alignment

You're using relaxed alignment. Once you've verified your mail setup, consider switching to strict alignment for better security.

Next Steps

Add this record to your domain's DNS as a TXT record, monitor the DMARC reports, and adjust your policy based on real-world results.
