I'm finishing converting from POP to IMAP and I'm seeing some potentially powerful uses, but I wonder if my ideas aren't more abuses.
I want to create 'multi-user' accounts that allow groups of users to archive and share emails with each other.

For example, in the case of a sales department, emails from customers may have requests for new product features. I could create an IMAP storage for sales that allows the sales staff to copy these requests into a common email account. These could then be sorted and searched by the product development team to better determine what customers want where product development should go.

Another example, a service/support group has some problem customers that frequently call multiple technicians for support. The service group can save all correspondence with this customer in a single location so they can better work together to provide support for this customer.

The possibilities for sharing emails in groups seem endless to me, but it depends on if it's a 'use' or 'abuse' of the IMAP protocol, and if Dovecot in-particular is designed to be able to handle this.

Thoughts?
