I'm preparing to move our site to dovecot 1.2.11 and have a question about shared folders. We're currently using UW imap's mbx mailboxes for shared folders. We accomplish the sharing by use of file system permissions and ACLs. I notice that dovecot's method of sharing is more based on IMAP ACLs and apparently file system permissions are useful, but not necessary. On the main dovecot page, it says: "Dovecot allows mailboxes and their indexes to be modified by multiple computers at the same time..." So, my question is whether I need to use the dovecot imap sharing namespace in order to safely share imap folders, or whether I can just use file system permissions as we have been using? My biggest concern is safe concurrent access to the shared folders, which I'm planning to implent with mbox files for now. thank you Tom Lieuallen Oregon State University College of Engineering

It's all safe. If you want per-user \seen flags then you need to set up per-user index files and currently it works only with maildir.
