I've already asked about it in the past, but since it came again, I
just wanted to add my wish for this (before I write a bigger message
on another subject). That's one of the features we're most missing -
mixing mboxes and Maildirs in the same namespace - that is due to the
fact that many users use such mailers like pine, mutt, etc. which
support it, and choose to keep some of their bigger mailboxes as
maildirs and their smaller ones as mbox, and except for at the time of
creation, it's relatively transparent.
Another wish would be a better form of cascading - subfolders as
subdirectories, instead of this awkward Maildir++ dot-separated
These two together will save me (and some user users who use IMAP in
addition to mutt or pine) the need to create two directory full of
symbolic links to access thei mail through IMAP.

Having looked again at the code, this does indeed not seem all that
easy. The code handling the mailbox namespace browsing seems too
tightly integrated with the code handling the mailboxes themselves.
I suppose it would be best if those two were separated, so a namespace
module will handle issues like "what subfolders does the folder Foo
have" and "what is the physical path for folder Foo.Bar", while the
mailbox module will handle issues like "what messages are there in
folder whose physical path is mail/.Foo.Bar" and "fetch the message
with UID 117 from the folder whose physical path is mail/.Foo.Bar".
The mailbox access module will query the namespace module to obtain
I'm not sure how much work this restructuring would be, but it will
definitely be useful, as it will enable adding different namespace
modules (with more flexibility) and different folder formats
separately in a cleaner way.
Which brings the subject of the next message I'm about to write to
Tom Alsberg - hacker (being the best description fitting this space)
