什么是 DKIM
定义
DKIM (DomainKeys Identified Mail) is a cryptographic signature added to a message with your domain’s private key. The receiver fetches the public key from DNS and verifies the message was not altered in transit and really came from your domain.
The public key is published in a TXT record like “selector._domainkey.domain”. The signature is added to the DKIM-Signature header by the sending server. YourTrend sets DKIM up automatically when you verify a domain.
