DKIM - DomainKeys Identified Mail is an email security tool that helps verify whether an email is genuinely from the sender it claims to be and hasn’t been tampered with during delivery.
Here’s a simple breakdown:
- How it works: DKIM adds a special digital signature to emails sent from your domain. This signature is like a seal of authenticity.
- Verification: When the email is received, the recipient’s email server checks the signature using your domain’s public key (stored in DNS) to confirm the email is legitimate and hasn’t been changed.
- Purpose: It helps prevent email spoofing (faking an email sender) and ensures email integrity.
Think of DKIM as a tamper-proof stamp on your email that shows it’s really from you and hasn’t been altered along the way!
