This allows to use S3-compatible object storage to offload blobs, making Postgres much lighter. We design for storing ~1B emails on a single instance.
We also take this opportunity to do model changes on blobs & attachments.
Migration 0027 is one-way, no going back after this one so check your backups.
This adds an intermediate Postgres-backed queue for inbound messages, that
allows us to run filters like spam processing before inserting messages in their
final storage (soon to be object storage). Also include misc. refactorings.
- Added multipart upload capabilities for EML and MBOX files to the
message imports bucket.
- Introduced new API endpoints for initiating uploads, completing
uploads, and aborting uploads.
- Updated serializers and viewsets to handle file uploads efficiently.
- Improved frontend components to display upload progress and handle
file uploads seamlessly.
- Adjusted backend services to process uploaded files asynchronously,
ensuring better performance and user experience.
- Updated documentation and tests to reflect the new functionality.
This fixes delivery errors seen in the wild where:
* Some servers advertise STARTTLS but have broken certificates.
Because of this, we follow Postfix's recommentations to use
opportunistic TLS by default.
* As we are sending emails straight to other SMTPs in direct mode,
we need to have stricter RFC compliance for our raw mime DATA, namely
CRLF endings and maximum line length. This was transparently done
by Postfix in relay mode.
Some env vars have also been renamed for clarity.
This PR adds support for 2 MTA out modes : Direct-to-MX and SMTP-relay outbound delivery. Direct mode supports SOCKS5 proxies, and we bundle a new `src/socks-proxy` component to support it.
We also add an end-to-end self-check command plus scheduled health-check task with optional Prometheus metrics.

When a message is received, if the auto labelling feature is enabled,
we try to add all relevant labels that are flagged for auto labelling to this
message.

We want to add ability to Messages to interop with our Drive application.
First, we want to be able to set the Drive base url through environment
variable then pass down Drive configuration to frontend through the config
api endpoint.

We are going to release a 0.1 version soon, along with our first production deployment. Starting from there, migrations and a consistent developer experience will be officially supported. To make that easier, this large patch cleans up several areas:
* Reset migrations one last time
* Update models for storage efficiency (move textchoices to integerchoices on high-volume tables)
* Use Blobs for mail mime data and draft bodies. Having them in a separate PG table is a first step, we will later start offloading them to object storage.
* Add default ZSTD compression to blobs
* Add per-domain DKIM Keys
* Add DNS check and provisioning, with a first Scaleway provider
* Fix Keycloak user provisioning
* Fix Attachment storage, they are now stored individually only at the drafting stage. Afterwards they are extracted from the main blob. This may be optimized later but at least we only store once. For JMAP compatibility, this requires using fake IDs in the blob API route.
* Add a management command and recurring task to retry unsent messages
* Improve the local developer experience with new ports and make commands
* Repackage MTA-in and MTA-out to be closer to Backend: Poetry, multi-step Dockerfile, move compose and makefile to the root
* Migrate to OpenSearch
* Improve overall documentation and add a self-hosting page
Contributes to #177 and #185
