Inbound Pipeline

How inbound mail is validated, parsed, sanitized, and persisted.

Processing flow

  1. Cloudflare Email Routing forwards inbound mail to the worker email handler.
  2. Address existence and sender-domain policy checks run first.
  3. MIME is parsed and HTML/text are sanitized.
  4. Metadata is persisted in D1; files are persisted in R2.
  5. Retrieval is guarded by organization scope.

Storage paths

Attachments are stored under:

TextText output example
email-attachments/<organizationId>/<addressId>/<emailId>/<attachmentId>-<filename>
