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.

Hi there, yeah i try it thanks for info :) can i ask about jmap future? I
think its rly cool protocol like imap + activesync but open source and more
standardized, for now only Cassandra have jmap?

Hi Ilya,

Guice apps had been architected in that exact way.

You can achieve the goal of building what we call "A tailor made server"
by writing your own assembly of guice module based on those defined in
https://github.com/apache/james-project/tree/master/server/container/guice
.

We as a project provide an example of such assembly:

https://github.com/apache/james-project/tree/master/examples/custom-james-assembly

This approach allows you to define only the components you want and
minimize classpath dependencies as well.

Is that your answer?

Best regards,

Benoit TELLIER

Well i personally find spring a little bit more stable than guice, but
there also cassandra app and pulsar smtp app

https://github.com/apache/james-project/tree/master/server%2Fapps%2Fscaling-pulsar-smtp
I sure puslar smtp can be done into fully mail combine. I really want
minimal solution. Just like gentoo works - completely cut off pop3 and
other stuff that not needed only imap,smtp and some other needed for full
working chain
How it can be done?

Hi Ilya,

I and LINAGORA company uses Distributed James server CF
https://james.staged.apache.org/james-distributed-app/3.8.1/index.html
which I would consider being most stable (with RabbitMQ). Though
dependencies are hard to set up, expensive to host and complicated to
operate, and are more suitable for bigger deployments.

An initiative with PGSQL is promissing but still young and likely not
mature enough.

Althouth being the current default option (thanks to its simplicity and
absence of external dependency) the JPA code is old and inefficient. I
did performance test this a few months ago and it was mostly okish but
to be fair I consider it mostly as "legacy".

And I would be happy to "kill" the Spring assembly :-)

That's for my thoughts and I would agree we would need to have a simpler
to consume output as a project: there's too many artefacts to choose
from and as a user it is hard to navigate.

Does this answer your question?

Regards,

Benoit

Hi there!
Benoit sorry for disturbing you with my bugs :)
Can i ask what better for stable production activemq, rabbitmq, pulsar
or
something else? How can i add this to typical james pack of programs?

Hi Eugen!

Thanks for the links.

I pledged for two books, one for me, one for LINAGORA as a company. Of
course this might get really handy for both Apache James and for
services we provide @LINAGORA.

    > I also plan to document the process and produce a guide that will

+1 !

Bonus point on my side to do it with the brand new PGSQL backend ;-)

Hi,

There is an ongoing campain for a book about self hosting an email
server.

It's not James specific but I believe it's of interest.
The author claims the book is ready and from what I saw / and
researched about him I trust he's speaking the truth.

I pledged to get the ebook and hope to self host by the end of the
year with Apache James.
I also plan to document the process and produce a guide that will
help
otehr people that wish to self host with James.

Consider getting the book if you are self hosting or want to support
more people self hosting.
