Frequently Asked Questions
1. What is the purpose of the Domain Scanner tool?
The Domain Scanner tool helps you analyze your domain's email authentication setup, including SPF, DKIM, and DMARC records, to ensure they are correctly configured and secure against email spoofing and phishing attacks.
2. How do SPF, DKIM, and DMARC work together?
SPF ensures that only authorized servers can send emails on behalf of your domain. DKIM verifies that the email content has not been altered during transit. DMARC ties SPF and DKIM together and provides policies for handling emails that fail these checks, while also generating reports for domain owners.
3. What does the risk assessment level mean?
The risk assessment level (Low, Medium, High) indicates the security posture of your domain based on the configuration of your SPF, DKIM, and DMARC records. A "Low" risk level means your domain is well-protected, while "High" suggests there are significant vulnerabilities that need addressing.
4. What should I do if my domain has a "High" or "Medium" risk level?
If your domain is assessed as "High" or "Medium" risk, you should review the specific issues highlighted in the scan and take steps to correct them. This may involve updating or creating SPF, DKIM, or DMARC records in your domain's DNS settings.
5. How often should I run the Domain Scanner?
It's recommended to use the Domain Scanner regularly, especially after making changes to your domain's DNS records or email infrastructure, to ensure your email security measures are up-to-date.
6. What happens if my domain lacks a DMARC record?
Without a DMARC record, your domain is vulnerable to email spoofing and phishing attacks. Implementing DMARC allows you to protect your domain by specifying how to handle emails that fail SPF or DKIM checks.
