Hi, I'm using dovecot as IMAP server. I access my mails trough Mail (Mac client), iPhone and webmail. In Mail I use a smartbox that shows all my unread messages, no matter where it is. I really want this feature at my iPhone, so I'm thinking about developing a plugin that will create the smart unread box and follow these rules:

• Every new mail arrived, it will create a hard link to directory .smart.unread (in case of Maildir);
• Every mark as unread, it will create a hard link;
• Every mark as read, it will remove the hard link;
• Every mail delete, it will remove all files with same inode.

This way, a smartbox with all unread messages will be available into webmail, iPhone and every IMAP client.

What do you think about it? Is there a simple way? If it is a cool feature, I'll develop it and post the plugin here.
