Validate mailbox before running tests

[dnsinit]

Would it be possible to validate pre-requisites for sending report by mail when the -MailRecipient parameter is used? As it is right now it runs all tests and then throws below error message only after it fails to send the mail.

{"error":{"code":"MailboxNotEnabledForRESTAPI","message":"The mailbox is either inactive, soft-deleted, or is
| hosted on-premise."}}
