DMARC (Domain-based Message Authentication, Reporting, and Conformance) records enhance email security and authentication, helping prevent email spoofing, phishing attacks, and domain impersonation.
Steps to Add DMARC Record:
1. Log in to JuJu Hosting Control Panel: Open your browser, visit the JuJu Hosting Control Panel login page, and enter your credentials.
2. Access DNS Management: Navigate to DNS Management or DNS Settings section.
3. Add DMARC Record:
- Locate your domain in DNS Management
- Click Add a Record or Add a DNS Record
- Select DMARC as the record type
- Configure the record:
* Name/Host/Alias: Enter domain or subdomain (use @ for root domain)
* TTL: Leave at default unless you have specific preferences
* Type: Choose DMARC
* TXT Data: Enter your DMARC policy as TXT record
Example DMARC Record:
v=DMARC1; p=none; sp=none; adkim=r; aspf=r; pct=100; fo=0; rf=afrf; ri=86400; rua=mailto:your@email.com
Key Components:
- v: DMARC version
- p: DMARC policy (none, quarantine, or reject) - use none for monitoring
- rua: Email address for DMARC reports
- ruf: Email address for forensic DMARC reports
- fo: Failure reporting options (typically 1)
- aspf: Align Sender Policy Framework (SPF)
- adkim: Align DomainKeys Identified Mail (DKIM)
4. Save Changes: Confirm and save the DMARC record to DNS settings.
Why DMARC is Essential:
- Email Authentication: Ensures only legitimate senders use your domain
- Email Deliverability: Enhances trust with email service providers
- Reporting: Provides insights into email delivery and suspicious activity
- Brand Protection: Prevents domain impersonation
Replace your@email.com with your actual email to receive DMARC reports.
