The set is regenerated before it is read, so a record that could not be built earlier appears once the missing configuration is in place. Each record carries the product it serves in `scope`, because a domain used for sending as well shares one merged set. Requires the `mailboxes:read` scope. ## OpenAPI ````yaml /api-reference/openapi.json get /api/v1/user/mailbox-domains/{id}/dns-records openapi: 3.0.0 info: title: Brudcast API version: 1.0.0 servers: - url: https://core-service.prod.brudcast.com description: Production security: [] tags: - name: Analytics x-displayName: Analytics - name: Campaigns x-displayName: Campaigns - name: Contacts x-displayName: Contacts - name: Mailboxes x-displayName: Mailboxes - name: Messages x-displayName: Messages - name: Sender Identities x-displayName: Sender Identities - name: Sending Domains x-displayName: Sending Domains - name: Templates x-displayName: Templates - name: Webhooks x-displayName: Webhooks paths: /api/v1/user/mailbox-domains/{id}/dns-records: get: tags: - Mailboxes summary: List mailbox domain DNS records description: >- Returns the DNS records the domain owner must publish for the domain to receive mail.
