Re: Book on how to run your own mail server

Good question ;-)

Yes that is exactly what JMAP is!

James supports JMAP with the cassandra backend and the (upcoming) 
PostgreSQL backend. It is not included in the JPA backend.

Short story long: in JMAP one can access messages with a global 
identifier, so independently of any mailbox. This was a big refactoring 
never undertook on top of the JPA implementation.

In case you look for a JMAP client, LINAGORA edits 
https://github.com/linagora/tmail-flutter/ which is compatible with 
Apache James (WebMail, Android, IOS). Also https://jmap.io is a good 
source of information on JMAP.

Best regards,
