Have you considered making dbox a major priority for v. 1.2?

I have been holding back on v.1.2 because I don’t really see the big
improvements in it that I saw in v.1.0 and v.1.1.
With 1.0 and 1.1 I hurried off using them in production environments even
while they where still in beta (of course only after proper testing)
because they posed so many advantages (primarily speed and stability) over
other solutions.

Since I’m focused almost entirely on stability and speed, and very little
on fancy functionality, what v.1.0 offers in terms of functionality is
just fine. What drove me towards 1.1 were speed improvements (and
stability on NFS).
I remember you made a post about not many people testing v.1.2.
I think the reason may be that most users feel the same as me. They’d like
to se a major feature that benefits their primary needs, which isn’t in
term of functionality but more in term of speed improvements.
Dbox could be that feature as I think there isn’t much room for further
developing the Maildir format (and as far as I can see you have gone as
far as possible with regards to optimizing speed while working within the
boundaries of the Maildir standard).

Maildir is nice compared to mbox but it really isn’t optimal. In days
where IOPS is the most difficult resource to get into your server (and
dovecot already using close to nothing in terms of CPU time and memory)
having one file per e-mail is less than sub-optimal especially when a
large amount of users just downloads the whole mailbox using POP3 (not to
mention backing up Maildirs).

Now don't take this as a critic, I love your software.
I just would really like to se dbox evolve and think it would be a major
driving force for v.1.2 :)

Develop dbox, Do it. Do it naoughw! (preferably pronounced with a
schwarzeneggerish accent like in the last three seconds of this splendid
video http://www.youtube.com/watch?v=adc3MSS5Ydc).
