v0.5.0

[0.5.0] - 2023-12-27

This version requires a database migration and introduces breaking changes in the configuration file. Please read the UPGRADING.md file for more information.

Added

• Performance enhancements:
  • Messages are parsed only once and their offsets stored in the database, which avoids having to parse them on every FETCH request.
  • Background full-text indexing.
  • Optimization of database access functions.
• Storage layer improvements:
  • In addition to FoundationDB and SQLite, now it is also possible to use RocksDB, PostgreSQL and mySQL as a storage backend.
  • Blobs can now be stored in any of the supported data stores, it is no longer limited to the file system or S3/MinIO.
  • Full-text searching con now be done internally or delegated to ElasticSearch.
  • Spam databases can now be stored in any of the supported data stores or Redis. It is no longer necessary to have an SQL server to use the spam filter.
• Internal directory:
  • User account, groups and mailing lists can now be managed directly from Stalwart without the need of an external LDAP or SQL directory.
  • HTTP API to manage users, groups, domains and mailing lists.
• LDAP bind authentication, to support some LDAP servers such as lldap which do not expose the userPassword attribute.
• Messages marked a spam by the spam filter can now be automatically moved to the account's Junk Mail folder.
• Automatic creation of JMAP identities.

Changed

Fixed

• Spamhaus DNSBL return codes.
