//! In-process `EmailSender` for integration tests.
|
|
//!
|
|
//! Captures every sent message in a moka cache keyed by normalised
|
|
//! recipient address. The test harness retrieves the captured payload
|
|
//! via the `GET /api/admin/smtp/test/captured` endpoint (only mounted
|
|
//! when `OXICLOUD_SMTP_MOCK=true`), parses the magic-link URL out of
|
|
//! the body, and follows it.
|
|
//!
|
|
//! # NOT for production
|
|
//!
|
|
//! The capture endpoint is admin-only AND only mounted in mock mode —
|
|
//! but even then, exposing inbox-style storage over HTTP is a leak
|
|
//! waiting to happen. The mock sender refuses to construct unless the
|
|
//! `OXICLOUD_SMTP_MOCK` env var is `true` at startup, so a misconfigured
|
|
//! prod deployment can't silently end up here.
