DKIM is specified in RFC 6376, and it is used by a number of email service providers, including Google, Yahoo, and Microsoft.DKIM is designed to address some of the flaws in the existing email system, such as spoofing, phishing, and message tampering. It allows email senders to digitally sign their messages in a way that can be verified by email receivers. This allows receivers to verify that the message truly came from the sender, and has not been tampered with.

How to modify DKIM for Siteguard if DKIM is not enabled by default

DKIM is by default enabled for your domains when using Siteground for your email transactions. But if you want to modify DKIM settings, do the following:

• Open your Siteground account and log in.
• Open Site Tools
• Go to Emails.
• Select Athentication > DKIM.
• Your domain names will have a DKIM status of “Active,” which allows you to manually disable them or modify your DKIM settings.

Remember, your DNS may take up to 72 hours to process the necessary DKIM record modifications once you make them.
