Set up fax-to-email

On top of the web inbox, Faxart can email each inbound fax to its recipient’s mailbox with the PDF attached. Delivery is internal-only, so PHI does not leave your tenant, and every send is audited.

How it works

When an inbound fax resolves to a mailbox, the broker queues an email with the PDF to that mailbox through your outbound relay. Recipients outside your internal domains get the web copy only, never an email, which is the guard that keeps PHI in the tenant.

Steps (Office 365 relay)

1. Create a licensed no-reply mailbox (e.g. faxart-noreply@your-domain) and enable SMTP AUTH for it.
2. Point the relay at Office 365:
   • FAXART_SMTP_RELAY_HOST=smtp.office365.com
   • FAXART_SMTP_RELAY_PORT=587
   • FAXART_SMTP_RELAY_STARTTLS=1
   • FAXART_SMTP_RELAY_USER / FAXART_SMTP_RELAY_PASSWORD (a secret at go-live)
3. Set FAXART_EMAIL_INTERNAL_DOMAINS to your accepted internal domains.
4. Send a test fax to a known internal DID and confirm the PDF lands in that mailbox with an EMAIL audit row. Confirm an external/unresolved recipient is not emailed and still appears in the web mailbox.

Notes

• Delivery runs on its own worker queue, so a slow relay never blocks fax transmission or classification.
• Leaving the relay host unset disables email delivery; the web mailbox still works.
• The local dev stack uses a bundled mail catcher in place of Office 365.
