[Dovecot] Migrating shared folders from courier-imap to dovecot

[Tom Clark]

Hi Timo,

I think I confused everyone by referring to them as shared folders (I was
using the Courier phrasing). 

I'm setting up Public Folders and then limiting access using ACLs. I can get
that far as to creating them, I'm just wondering if there was a specific way
to migrate from Courier's "public" folders to Dovecot's public folder
system, or is it just a case of dropping the mail in?

Am I right in thinking Dovecot doesn't have the "cur" and "new" folders on
Public folders? If so, we used qmail-deliver (with the -c flag) to deliver
our mail into the public folders, how should I go about delivering the mail
into those folders?

Thanks,

Tom

Did you want per-user flags with shared folders? IIRC Courier used some
weird symlink directory for that, which won't work with Dovecot.
http://wiki2.dovecot.org/SharedMailboxes lists all the ways you can
currently do shared folders with Dovecot.
