If you already use DKIM in your domain (with another email system), you must generate a new, unique domain key to use with Gmail. Domain keys include a text string called the selector prefix, which you can modify when you generate the key. The default selector prefix for the G Suite domain key is google.
How to set up DKIM to prevent email spoofing?
About DKIM. DKIM uses a pair of keys, one private and one public, to verify messages. Generate a private domain key, which adds an encrypted header to all outgoing messages sent from your G Suite domain. 2048-bit domain keys are more secure than 1024-bit domain keys. If your registrars support 2048-bit keys, we recommend using them.
