Looking back through the mail, I found the following from March

The way this worked at one point was by making each user have separate
index file for the mailbox, then keeping the \Seen flag only inside that
index file and ignoring the maildir's seen flag completely. Then I
rewrote the maildir syncing code and this part was dropped out. Probably
wouldn't be too difficult to make it work again.. Yea, looks like it
wasn't. Works now in CVS.

I'm trying to do a similar thing now, but without 100% luck. I have
the following namespaces defined

namespace public {
   separator = /
   prefix = Public/
   location =
maildir:/var/mail/scouts/public:CONTROL=/var/mail/scouts/%1n/%n/shared-settings/public/control:INDEX=/var/mail/scouts/%1n/%n/shared-settings/public/index
   hidden = no
}

namespace public {
   separator = /
   prefix = Official/
   location =
maildir:/var/mail/scouts/official::INDEX=/var/mail/scouts/%1n/%n/shared-settings/official/index
   hidden = no
}

Even though I have separate INDEX's for the second public namespace,
the SEEN flag doesn't seem to be picked up from the users' INDEX's.
BUT, for the first namespace, when I have CONTROL defined as well, it
IS picked up!

The reason I don't want CONTROL defined for the second name space, is
I discovered that I can force all users on the system, to be
subscribed to mailboxes in the 'Official' name space, if I keep
CONTROL with the mailbox, instead of separate, and ensure that once I
have set up the subscriptions file, I ensure it can't be changed.
The counter side of this 'subscriptions' hack, is that I can't do
hidden=yes.
Ideally, I want a method of forcing a subscription on every user, that
they can't change, but still preserving the SEEN flag. The closest I
have come to, is, separate CONTROL, INDEX, and hidden=yes. This
requires though, that I use the SquirrelMail forced subscriptions
extension, which I've not yet tested.
The other idea I had, was a method for having subscriptions come out
of a database, seeing as I already have a large block of user data in
the SQL database, and if I could have subscriptions in there as well,
that would be a huge bonus! (Even better if it was only for the
namespaces I wanted, cause I don't need to put each users personal
subscriptions in a database).

Anyway, it's mainly ideas, other than the SEEN flag issue I described
above. Hope someone has ideas for getting it to work.
