The Apache James developers are pleased to announce James server 3.4.0 release.

Here are some points we worked on:

Added

• Add in-memory docker image
• Support of AWS S3 as blobstore
• WebAdmin routes for mapping management (AddAddressMapping, AddRegexMapping, ListMappings), previously only manageable by CLI
• Metrics for Deleted Message Vault
• More metrics for BlobStore (new delete & deleteBucket configuration)

Changed

• (experimental) New implementation of the deleted message vault on top of an object store, not relying anymore on a repository. This avoids exposing messages via webAdmin. Messages previously stored in the vault will be lost.
• Migration to ElasticSearch 6.3
• Blob export to LinShare
• Native DKIM support for outgoing mails. The mailets from james-jdkim have been included in main James project.

Deprecated

• Zookeeper component. This will be removed after 3.4 release. If you have development skills, and are willing to maintain this component, please reach us.

Removed

• Karaf OSGi implementation. It was not compiled nor tested for a year. We didn’t get any feedback about that and we don’t have the resources nor the skills to maintain it any more.

Early adopters can download it, any issue can be reported on our issue tracker.
