What are the custom MX settings for email on Gmail-managed domains?

I will be registering a new domain in order to beta test the hosting service and using Gmail to manage the email for this domain.

I have not been able to find anything pointing to the custom MX settings that we'll need to use in order to do this.

Thanks in advance for any assistance someone might be able to provide in pointing me in the right direction :slight_smile:

Sue.
