Stay tuned as we discuss changing the ‘mailed-by:’ field in your emails. We’ll explore the steps involved and why it’s important for email security. Stay tuned for more insights!
What Is The ‘mailed-By:’ Field, And Why Is It Important In Email Authentication?
The ‘mailed-by:’ field is a part of an email header that shows the domain responsible for sending the email. This field helps identify which server sent the email, which is crucial for verifying its authenticity. The ‘mailed-by:’ field helps prevent email spoofing and phishing attacks by ensuring that emails come from trusted domains.
Properly configuring this field through DKIM (DomainKeys Identified Mail) enhances email security and improves deliverability, making it a key component in maintaining a trustworthy email system.
DKIM And Its Role In Email Authentication – How To Change The ‘mailed-By:’ Field!
DKIM (DomainKeys Identified Mail) is an email authentication method that allows the receiver to check that an email claiming to come from a specific domain is indeed authorised by the domain owner. It involves adding a digital signature to the email, which is then verified by the recipient’s mail server.
Key Components Of DKIM:
- Public Key: Stored in the DNS records of the sender’s domain, the public key allows recipients to verify the email’s signature.
- Private Key: Used by the sender’s mail server to sign the email, ensuring that it hasn’t been altered during transmission.
- Selector: A unique identifier that helps locate the DKIM public key in the DNS records.
- Signature Header: Includes the cryptographic signature that proves the email’s authenticity.
- Canonicalisation: Refers to the process of standardising the email header and body before signing, ensuring consistency in the DKIM signature.
- DKIM Record: A DNS TXT record containing the public key and other DKIM settings required for email verification.

Enhanced Security:
Updating this field helps prevent email spoofing and phishing attacks by ensuring that emails are authenticated and verifiable, protecting both your brand and your recipients. Proper email authentication methods, such as DKIM, provide an additional layer of security against fraudulent activities. This practice helps safeguard sensitive information and maintain the integrity of your communications.
Compliance with Best Practices:
Adhering to email authentication standards, including updating the ‘mailed-by:’ field, aligns with industry best practices for email security. It demonstrates your commitment to maintaining secure and trustworthy email practices, which is crucial for compliance with regulatory requirements. Implementing these best practices helps protect against various email-related threats.
Streamlined Troubleshooting:
Having a properly configured ‘mailed-by:’ field makes it easier to troubleshoot email delivery issues. When problems arise, clear and accurate email headers simplify the process of diagnosing and resolving issues. This efficiency ensures that your email system runs smoothly and reduces downtime.
How To Change The ‘mailed-By:’ Field? – Step-By-Step Guide!
Accessing Your Domain’s DNS Settings:
The first step in changing the ‘mailed-by:’ field is to access your domain’s DNS settings. This is typically done through your domain registrar or DNS hosting provider. Once logged in, you must locate the section where DNS records are managed.
- Log in to your domain registrar (e.g., GoDaddy, Namecheap) or DNS hosting provider (e.g., Cloudflare).
- Navigate to the DNS management section.
- Look for existing DKIM records or add new ones.
Updating DKIM Records:
To modify the ‘mailed-by:’ field, you must update your DKIM records. This usually involves creating or modifying a TXT record in your DNS settings.
- Identify the selector used for your DKIM record.
- Add a new TXT record with the correct DKIM information in your DNS settings.
- Ensure the DKIM record is formatted correctly and points to the correct public key.
Configuring Your Email Server:
After updating your DNS records, you must configure your email server to ensure it uses the correct DKIM signature.
- Log in to your email server’s admin panel (e.g., Google Workspace, Microsoft 365).
- Navigate to the email authentication settings.
- Update the DKIM settings to match the new DNS records.
Verifying the Changes:
Once you’ve made the necessary changes, verifying everything is working correctly is important.
- Send test emails to ensure the ‘mailed-by:’ field reflects the correct domain.
- Use online tools like MXToolbox or DKIM Validator to check your DKIM configuration.
- Review the email headers to confirm the ‘mailed-by:’ field has been updated.
What Are The Advanced Considerations And Best Practices For Changing The ‘mailed-By:’ Field?
- Choosing the Right Selector: Select the appropriate DKIM selector to manage multiple keys and ensure older emails remain verifiable after key changes. This helps maintain consistent authentication across different key versions.
- Rotating DKIM Keys Regularly: Rotate DKIM keys regularly to enhance security and reduce risks if a key is compromised. This practice minimises potential vulnerabilities in your email authentication.
- Handling Multiple Domains: Set up DKIM for each domain individually to prevent misconfigurations and ensure accurate authentication. This approach supports effective email verification for all domains you manage.
- Monitoring DKIM Performance: Track DKIM performance to address signature issues and maintain effective email authentication. Monitoring helps quickly resolve authentication problems and improve email deliverability.
- Keeping DNS Records Updated: Ensure DKIM DNS records are current to avoid authentication failures and maintain email integrity. Regular updates prevent disruptions in email verification and support smooth email operations.
- Implementing SPF and DMARC: Combine DKIM with SPF and DMARC for comprehensive email security. Implementing these protocols together enhances protection against spoofing and phishing attempts.

Common Challenges And How To Overcome Them
Incorrect DNS Records:
Misconfigured DKIM DNS records can lead to authentication failures. To overcome this challenge, double-check your DNS entries for accuracy and ensure the DKIM public key matches the private key used for signing. Utilising DNS lookup tools can help verify your records’ correctness and prevent email verification issues.
Key Rotation Issues:
Problems can arise when rotating DKIM keys, such as old keys still being used. To address this, implement a clear key rotation policy and promptly update your DNS records to reflect new keys. Effective communication within your team about key changes is crucial for maintaining consistency and avoiding disruptions.
Email Deliverability Problems:
Despite the correct DKIM setup, emails might still be marked as spam. To improve deliverability, review and optimise your email content and sending practices. Combining DKIM with SPF and DMARC can enhance email security and ensure your messages reach the intended recipients.
Multiple Domain Management:
Managing DKIM for multiple domains can lead to configuration errors. To streamline the process, implement a structured approach for handling DKIM settings for each domain separately. Centralised management tools can help manage multiple domains more effectively and reduce the risk of misconfigurations.
Monitoring and Reporting:
Tracking DKIM performance and identifying issues can be challenging. Overcome this using monitoring tools and services to regularly check DKIM status and receive alerts for potential problems. Analysing reports helps address authentication issues promptly and maintains effective email security.
