What is the easiest way to enable users to mark messages on IMAP server. We have setup where multiple users are monitoring one Inbox, and when message comes, someone should "take" it, or asign it to someone, something like a task.
Just prepending or appending user name to subject would be enough. This however has to be done in a way that all other users see this. Flags system with only one flag and without words is not enough.
Is there email client which allows this or it has to be server side configured? If I have to go server side route please post some guidelines.
