经常被问到的问题

How does a DMARC record work, and what does it do? - A DMARC record helps email receivers determine what to do with emails that fail SPF or DKIM checks. It enhances email security by preventing email spoofing, phishing attacks, and other forms of abuse.
Can I have multiple DMARC records for one domain? - No, it's recommended to have only one DMARC record per domain. Having multiple DMARC records can lead to unpredictable behaviors and make it difficult for receiving servers to determine which policy to apply, potentially affecting your email deliverability.
How long does it take for a DMARC record to take effect? - The propagation of a new or updated DMARC record can vary, typically taking from a few minutes to 48 hours. It depends on the TTL value and the caching policies of DNS resolvers.

Can I use DMARC if I don't have SPF or DKIM set up? - Yes, you can implement DMARC with a policy of none (monitoring mode) to receive reports without affecting your email delivery. However, for DMARC to be fully effective in preventing spoofing and phishing, it's recommended to have both SPF and DKIM in place.
What should I do if I'm not receiving DMARC reports? - Ensure your DMARC record is correctly formatted and published. Check the rua (for aggregate reports) and ruf (for forensic reports) tags in your DMARC record to ensure the email addresses are correct and capable of receiving reports. Contact your email service provider if issues persist.
Can changing my DMARC policy affect my email delivery? - Yes, moving from a none policy to quarantine or reject can affect email delivery if legitimate emails fail SPF and DKIM checks. It's important to monitor reports and adjust your SPF and DKIM configurations before tightening your DMARC policy.
