Modern email is a primary target for cybercriminals, who exploit vulnerabilities to impersonate domains, intercept messages, and launch phishing attacks.
DKIM (DomainKeys Identified Mail), DMARC (Domain-based Message Authentication, Reporting & Conformance), and MTA-STS (Mail Transfer Agent Strict Transport Security) are essential standards that work together to secure email communications and protect brands, users, and sensitive data.
Why you need these technologies
-
DKIM adds a digital signature to outgoing emails, allowing recipients to verify that the message was genuinely sent from the claimed domain and has not been altered in transit.
-
DMARC builds on DKIM and SPF (Sender Policy Framework) by providing instructions to receiving mail servers on how to handle messages that fail authentication, and generates reports for domain owners.
-
MTA-STS ensures that emails sent to your domain are only transmitted over encrypted channels, preventing attackers from intercepting or tampering with messages during transit.
Risks of not implementing DKIM, DMARC and MTA-STS
-
Increased phishing and spoofing: Attackers can send emails that appear to come from your domain, tricking recipients into divulging sensitive information or spreading malware.
-
Loss of brand trust: Customers and partners may lose confidence in your communications if they receive fraudulent emails purporting to be from your domain.
-
Data breaches: Without encrypted transport (MTA-STS), emails can be intercepted and read by malicious actors.
-
Poor deliverability: Major email providers may flag or reject your messages if your domain lacks proper authentication, leading to lost business opportunities.
-
Lack of visibility: Without DMARC, you won’t know who is sending emails on behalf of your domain or whether your policies are effective.
With Blue Car Technologies eMail protection services, we can implement DKIM, DMARC and MTA-STS services on your domain, and ensure your eMail services and brand reputation are protected. Adopting this approach will give you:
-
Protection Against Email Spoofing and Phishing
-
Prevents unauthorized parties from sending emails that appear to come from your domain, reducing the risk of phishing attacks.

Authenticated emails are more likely to reach inboxes rather than being marked as spam or rejected by receiving mail servers.
-
-
Enhanced Brand Reputation and Customer Trust
-
Demonstrates your commitment to security, reassuring customers and partners that your communications are legitimate.
-
-
Visibility and Reporting
-
DMARC provides detailed reports on email sent from your domain, helping you monitor abuse and improve your authentication posture.
-
-
Secure Email Transmission
-
MTA-STS enforces encrypted delivery, protecting emails from interception and tampering during transit.
-
Implementing DKIM, DMARC, and MTA-STS is now considered best practice for any organization that values secure, reliable, and trusted email communications.
