Alex,
I was in a similar situation a year ago, and my solution was to alter
the behaviour of courier-imap as a workaround. I know how to write,
debug and modify code, and since Sam's code is clear and well written it
wasn't that difficult. A patch is attached to this mail which would
apply cleanly to courier-imap 1.4.0. I have been running this since
1.3.7 was released (more than half a year). I still regard outlook to be
broken in this regard, but since smooth migration (from an uw-imap
installation) was a high priority, I didn't really have much of a
choice. Never the less, I highly respect Sam's decision to not address
this need in his code base. But since it's open source (thank god for
that, it have saved me a lot of headache!) nothing stops you from
applying inofficial patches like this one.
Things to be aware of with this patch in particular:
1) I had to change the namespace prefix for shared folders from "shared"
to "#shared" (a la uw-imap) in order to avoid a potential folder name
conflict.
2) The top level personal folder behaviour is not active by default. You
need to put a line with "IMAP_PERSONAL_NAMESPACE_AT_TOP_LEVEL=1" in your
imapd configuration file.
3) This alternate behaviour has not been tested together with the use of
shared folders.
Hope it helps.
Regards, Tomas
