Hey HN,

I’d like to share an open-source project I’ve created. It is an email archiving tool that can back up your whole email system with full-text search capabilities.

The project is called Open Archiver, and it is able to archive and index emails from cloud-based email inboxes, including Google Workspace, Microsoft 365, and any IMAP-enabled email inbox. You can connect it to your email provider, and it copies every single incoming and outgoing email into a secure archive that you control (Your local storage or S3-compatible storage).

Some features:

- Archive and index all emails and attachments

- Import and sync the whole organization's emails: For Google Workspace and MS 365, Open Archiver can ingest all individual inboxes' emails

- PST and .eml files import

- Role-based access

- Full-text search: All archived emails and attachments are indexed, so you can search the content of all emails and attachments

- You can choose to store your files either on your local machine or on any S3-compatible storage provider

- API access

It's AGPL-3.0 licensed and free to use for personal and business purposes. I'd be happy if you could give it a try and give me some feedback.

You can find the project on GitHub (with Demo site): https://github.com/LogicLabs-OU/OpenArchiver

This looks really great, I'm not sure how easy it would be but oauth for consumer outlook, Gmail and yahoo would be a great addition.

For now, you can connect to these email providers with IMAP using app passwords. But oauth connection is a planned feature because Outlook seems to have disabled password connection for IMAP.
