SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

mailescrow provides a safe, human-supervised path for sending and receiving emails via a REST API, ensuring that outbound messages cannot be sent without explicit human approval and inbound messages are surfaced only after human review.

Core Features & Use Cases

  • Outbound emails are queued and require a human to approve or reject in a web UI before being sent via SMTP.
  • Inbound emails are captured via IMAP poll and presented for approval, then retrieved via API once approved.
  • The solution exposes a REST API for programmatic submission and retrieval; a web UI provides the approval workflow; IMAP folders track lifecycle; and SQLite persists emails.

Quick Start

Submit an outbound email via the REST API and approve it in the web UI to send.

Frequently Asked Questions about mailescrow

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add a human approval step before sending emails via a REST API?▼

To add a human approval step to email workflows, outbound messages submitted via a REST API are queued in a web UI where a human must explicitly approve or reject them before they are sent via SMTP.

What is a human-in-the-loop email proxy and how does it handle inbound emails?▼

A human-in-the-loop email proxy captures inbound emails via IMAP poll and presents them in a web UI for human review, making them available for retrieval via API only after they have been explicitly approved.

Can I integrate IMAP and SMTP workflows with a human approval gate for production use?▼

Yes, you can integrate IMAP and SMTP workflows with a human approval gate using SQLite persistence, ensuring production-grade email queuing and state tracking for both inbound and outbound messages.

What's the best way to queue outbound SMTP emails for manual review before dispatch?▼

The best way to queue outbound SMTP emails for manual review is to submit them through a REST API that stores messages in SQLite, surfacing them in a web UI for human approval before final SMTP delivery.

How do I retrieve approved inbound emails via API after IMAP polling?▼

You retrieve approved inbound emails by polling an IMAP folder that tracks the message lifecycle; once an email is approved in the web UI, it becomes accessible for retrieval through the REST API.

Do I need a database to persist email approval states in a human-in-the-loop workflow?▼

Yes, SQLite is used to persist email approval states and lifecycle data, ensuring that queued inbound and outbound emails are reliably tracked across the REST API and web UI.
