What is DKIM? DomainKeys Identified Mail explained (in under 4 minutes)

DKIM (DomainKeys Identified Mail) is an email authentication method that uses public-key cryptography to sign emails and verify that the message body and attachments were not altered in transit.

Spammers and hackers might try to intercept your messages and send malicious emails on behalf of your domain, which will damage your email security and overall domain reputation. And if a lot of people start receiving fraudulent messages that look like they’re coming from you, they will get annoyed and send them straight to the spam folder—so you might find yourself on a list of bad senders you should not have been on in the first place.
