> The Mailbox event system is limited to one James instance. This means if a user is connected on a server A and if a mail arrives for him on server B, he will not get the notification.
> This means we need to send events to a message queue, so that they can be treated remotely by other James server to send IMAP notifications.
> But we need to be carefull : we must not trigger some Listener : eg : Event must be treated only once by MessageSearchIndex.
> What we can first notice is that Listener that must be triggered only once are Global Listeners, other are per mailbox registered.
> What we just need to do is :
>
> - send event in a per mailbox topic ( so that no James server will have scalibility trubbles ). Imap subscription will be listening the topic of the mailbox they are targeting threw the message queue. Global listener are called only once on the server submitting the event.
> Of course I will provide Spring defined beans and optionnal separated classes.
> What do you think of it ?
