Successful upgrade from 2.2.3 to 2.3.1 but...

[Skip Morse]

So... this seems like it was pretty straight forward, this was just a
test run (in a test VM), but after one more practice, I'm thinking it
will probably take me about 30 minutes (if that) to do the production
upgrade (not counting the backup first).

Here are my concerns before i can really flip the switch.

First issue:

Part of our usage requires that we are able to have email delivered to
shared folders.  I've always had to use the workaround(s) found here:
http://wiki.kolab.org/Shared_folders

Most recently, changing the line in ldapvirtual.cf to: query_filter =
(&(!(kolabDeleteFlag=*))(|(alias=%s)(mail=%s)))

The above line allows sending to a shared folder, but I didn't see any
updates on the wiki and it turns out that there's something wrong with
the 'receiving' to a shared folder.  All mails sent to the shared
folder are stuck in the postfix queue with a temporary failure, and I
can't tell from the postfix log why.  Just messages like this:

<info> postfix/pipe[16637]: D747BB1D7A:
to=<kolab+shared.scheduling at domain.com>, relay=kolabmailboxfilter,
delay=1.2, delays=0.05/0.06/0/1.1, dsn=4.3.0, status=deferred
(temporary failure)

It's the same result if I send directly to
kolab+shared.blah at domain.com or if I send to the alias that's in the
'vcard' in the address book entry.  There is one line in the wiki that
I don't quite understand, so maybe this is my answer if anyone has any
expansion on what this means:

04/30/2010 - diegows: You have to give post permission to kolab user
in the shared folder too.

I do have 'anyone' with the 'post' permissions.  Maybe that is no longer enough?

** As a note, regular user to user mail seems to work fine

Second issue:

Is the web client limited to only the dynamic view now?  I don't hate
it, but I like the option.  While testing, I happened to log in as a
user with an outrages amount of top level folders.  This causes some
folders to not even be viewable and as far as I can tell, no way to
get to them.  I also couldn't find any settings in the per-user,
global options to select which layout, maybe i missed it?

Almost all of our users use Outlook and the Toltec connector, so it
isn't a huge problem for most.  But I would like to imagine that we'll
migrate most users to the webclient at some point and this may be a
deal-breaker...

Thoughts/Advice?

Any help is always appreciated.
