DomainKeys Identified Mail (DKIM) is a method for authenticating emails. DKIM adds a digital signature to your outgoing emails, allowing recipients’ email servers to verify that the messages come from a legitimate sender and haven’t been altered on the way. Setting up DKIM for your email server, such as Plesk, can enhance your email deliverability and protect your domain’s reputation from being used for phishing or spamming. With this post, you will get your answer on how to set up DKIM for Plesk.
