Outgoing Mail Settings Improvement

Would be great to see some additional functionality in aXcelerate's  Web & Other Integrations>Outgoing Mail Settings>Sending Options.  An additional feature when you 'add new' domain to the domain whitelist, whereby aXcelerate could trigger a process to approve the relationship between aXcelerate and the recipient's domain.   This could allow for end customer domains to be verified and onboarded with aXcelerate. It would improve the mail server reputation issue experienced and be an additional system benefit in terms of a professional onboarding experience followed by a seamless customer experience for aXcelerate tenants and their partners. Similar validation and authorization exists for other multi-tenant services which verify individual sender addresses or customer domains and can be conducted programmatically (see - https://docs.aws.amazon.com/ses/latest/dg/creating-identities.html#default-config-set-at-create-api)
