Newer than the one I've been using up to now (and, actually, continuing to
use). (kmail 1.13.7 on Debian Wheezy).

I've spent a long time (I don't want to admit how long -- close to 18 years)
building, essentially, a free format database (sort of an askSam workalike)
using mbox as the basic framework. I've got semi-working versions using kate
as the editor, now working on building an editor based on scintilla -- very
slow going.
I intend to allow records (essentially in the format of emails) to be
intermixed with real emails in mbox files.

Hmm, I have no idea how to create "a new user defined resource for receiving
(and storing) mails". I've tried googling, and, so far, nothing makes sense
to me.
