       In, #ActivityPub server-to-server communication, a server read outbox of another server periodically? Or is there any event for triggering this? Or I'm totally wrong?

       @veer66 Why do you think you need to periodically check another server's outbox? If you're a server, theoretically you only care about what arrives in your inbox.

       @mariusor Another server knows which inbox to deliver from follower collections, doesn't it?

       @veer66 In short, the server that has a local activity created by one of its actors retrieves the actors that the activity is addressed to, and adds their inboxes to a list, performs a normalization on that list (we don't want to send twice to the same inbox) and then delivers to each of them a copy of the activity with a  corresponding authentication mechanism.For more details see the spec: [1] https://www.w3.org/TR/activitypub/#delivery [2] https://www.w3.org/TR/activitystreams-vocabulary/#audienceTargeting

       @mariusor Thank you. Actually I read the spec last night but I didn't understand. Your explanation helps making it clearer.

       @veer66 for some more fancy normalization, a server might remove individual actors' inboxes that have a "sharedInbox" that matches another element in the addressing list.

       @mariusor This is very important. So there is no need to send many duplicated activities from server to server, isn't it?
