dovecot - Aug 2010 - My "%%" variables in the namespace settings do not appear to be expanding.

Hello,

    I've been using the dovecot 1.2.x branch server software for a
    while now.  With the advent of the 2.0.x branch going 'stable' I
    decided to attempt a migration and make use of some of the features
    that I've not needed before.  One of these is the shared
    folder/namespace feature.  No luck.  I've hit a wall and can not
    determine the problem.  At the moment it looks like a bug to me,
    but it may well be that I'm missing some related configuration, or
    file permission.

    I can not get the %% variable expansion in a namespace to work.
    What I end up with, on an IMAP connection is a directory named, for
    instance, '%h'.  The same goes for any of the %% variables used at
    this point.  My current set-up is 'not' the same as the current
    setup and I'm using virtual users that are not 'live' on the
    current system.

    I would really appreciate it if someone could cast an eye over my
    config and let me know if I've missed something obvious.

    Thanks.

Set mail_debug=yes. What does it log when 1) logging in and 2) when it
creates the %% directory (or is that also on login)?

prefix = shared.%u.

Although this won't work well because your username most likely has
'.'
characters. The only good solution would be to change all separators to
'/', but that can then cause problems with existing clients that use
your system (possibly requiring some kind of client cache refresh /
account recreation).

This is ok.

This doesn't much make sense and I doubt Dovecot actually uses it for
anything. Just remove it.

I forgot, prefix here should contain %%u, not %u, because %u gets
expanded to your own username while you want it to be expanding to other
users' username.. I'll add a check against this.
