reliable, 3rd-party-accessible and a non-proprietary store, a surprising
number of corporations would be very interested.

Can any of the evolution hackers address this? Obviously, as GPL'd software,
it's automatically non-propriertary, and I'm sure the conversion tools will
be in place to make it third-party accessable (in a worst case scenario, the
third party has the source code...), but specifically, what format is it,
and what are the expectations as to scalability/speed? Is the current format
a temp solution or the long term fix?

I should have cc'd the list on this I guess...

Basically, Evolution uses the Unix mbox standard format by default and
can/does support other formats currently such as MH and Maildir. It
would be possible to write an SQL provider as well, but we haven't yet
done it because it's not a high priority. Mbox scales pretty damn well
with our indexing in place, Evolution should be able to handle 40+ megs
of mail without a problem (and I know it does because we've tested it).
Evolution is VERY fast in this reguard.


Even more. I'm using evolution with reiserfs. The combination of
maildir, dbm files and reiserfs should have no real limit in the size of
mailboxes. Even operations of all files in a mailbox are really fast
(from my subjective tests with mbox and maildir).
Experienced with my tests with reisefs (up to 250,000 files in one
directory) I think this kind of configuration is fast up to some 10,000
of files and relatively independent of the size of the mails.

I hope, evolution will improve further ;-)
