Whitelabeling DNS records

First make sure your own domain is verified using the SPF, DKIM, and Tracking records on the Domain Verification Guide - Your own customers can then add the following to their own DNS.

SPF

Name: @

Type: TXT

Value: v=spf1 a mx include:yourresellerdomain.com ~all

Tracking

Name: tracking

Type : CNAME

Value: tracking.yourresellerdomain.com

Do not change DKIM entry.
