james has quite a lot of code (for a FOSS java project) so i'll try to
help you get started...
the IMAP code is in a separate project but ATM this project doesn't
contain the socket work required to create a standalone IMAP server.
(though it could be easily added as a separate module.)
http://svn.apache.org/repos/asf/james/protocols/current/ uses
externals to create a virtual structure containing the server and imap
projects. if you don' t mind a big checkout, that'd be a good place to
start.
please keep in mind that the glue code is poor quality and overdue
replacement (perhaps by something spring-based)

the way i see things:
JCR is more document-centric. this makes integration with
document-centric applications easier.
JPA integrates better with traditional RDBMS applications.
but other people may well have other perspectives...

Interesting comment below on the use of JCR (hierarchical schemata) or a
JPA implementation. (RDBMS)
What would you consider the pro/con argument of one vs the other?

James IMAP is a complete implementation of RFC2060 (RFC3501 requires
StartTLS which is yet to be implemented). the internal APIs need
revising, as does some of the design but the basics are done and -
most importantly - the functional testing suite is ok.
there is quite a lot more to be done on IMAP
the easiest task - but maybe not the quickest - is upgrade everything
to Java 1.5 (generics etc)
the Torque store is really just legacy: this needs to be replaced by
JCR and JPA storage. the JPA stuff is working but more design
refinement is required and the extraction of a framework that can also
be reused by the JCR storage. the JCR should follow quite quickly once
that's done.
StartTLS is needed
there are also quite a few extension RFCs related to IMAP which should be added.
anything here take your fancy?

I am interested. I do not know too much about JPA, or IMAP for that matter. But I think that implementing IMAP would help JAMES be competitive in the Cloud 2.0 era.

Is there support for Maildir at this point? Goal is to use James from
SMTP (incoming mail from servers and outgoing to relay with
authentication) over SSL and TLS with IMAPS and LDAP authentication.
How achievable is this at this point?

IMAP is complex and has very specific storage requirements. porting
the avalon DB repository to JPA should be much easier but isn't on my
agenda today.
if anyone wants to volunteer to develop a repository i'd be very happy
to review contributions and help out with design etc. anyone
interested?

this is a JPA port (and not an EJB3 one) but is a step in that
direction. (hopefully David or Bernt might in with more information on
james-in-geronimo.) my initial aim is to support standalone JPA with
naive pooling (but hopefully it shouldn't be too difficult to move to
EJB3).
there are a couple of wrinkles with Hibernate:
1. using LGPL'd software is difficult here at apache. the legal stance
has become more nuanced in recent times but AIUI it's not completely
settled yet. (this isn't an unsummountable issue)
2. i'm a big OpenJPA fan so i find very little motivation in working
on hibernate. so, interested developers would need to step up.

Forgive me if this is already answered... I looked and did not see it.
(just joined the list).
Would it be appropriate to look at EJB3 with a Hibernate provider at
least a a compatibility test case in addition to openejb.org baesd on
1. A double check for sanity and 2. knowledge that Hibernate is
prevalent in the industry as a provider behind EBJ3.
