Getting Apache James to serve 1M+ digital mailboxes of all Estonian residents
summary
A national digital-mail system serves all Estonian residents — about 1.3M mailboxes — built in one year and going live at month end, using Apache James as the mail backend, Apache Cassandra for distributed indexing and S3 for message storage, with Elasticsearch for search and message queues (ActiveMQ/RabbitMQ). Front end talks JMAP via a client library, calendar events integrate with Google/Outlook, several PRs land upstream (including an Elasticsearch bump), custom extensions deploy into James, and the deployment is production-ready.
