Those attempting to understand these message flows should become familiar with (at the minimum) the [DFRN protocol document](https://github.com/friendica/friendica/blob/stable/spec/dfrn2.pdf) and the message passing elements of the OStatus stack (salmon and Pubsubhubbub).
-Most message passing involves the file include/items.php, which has functions for several feed-related import/export activities.
-
When a message is posted, all immediate deliveries to all networks are made using include/notifier.php, which chooses how (and to whom) to deliver the message.
This file also invokes the local side of all deliveries including DFRN-notify.
