Introduction to DKIM
Welcome to the world of DKIM (DomainKeys Identified Mail). Think of DKIM as the digital seal on your email envelopes. It ensures authenticity and guards against tampering.
What is DKIM?
DKIM adds an extra layer of security by digitally signing outgoing emails. It’s like sealing an envelope with a cryptographic stamp.
How Does DKIM Work?
- Digital Signatures: The sending mail server generates a unique cryptographic signature for each outgoing email. This signature is embedded in the email header.
- Verification Process: The receiving mail server retrieves the DKIM signature from the email header and verifies it against the public key stored in the sender’s DNS records.
- Impact on Deliverability: DKIM prevents tampering with email content during transit and enhances sender reputation.
Why DKIM Matters
- Ensure Authenticity: Recipients can trust that your emails come from a verified source.
- Guard Against Tampering: DKIM prevents unauthorized alterations during transit.
- Improve Deliverability: Email providers favor DKIM-signed messages.
