+# Introduction
+
+This module closes s2s connections when
+[mod_smacks][doc:modules:mod_smacks] reports that a connection has not
+received a timely acknowledgement as requested, indicating that the
+connection is broken or the remote server is not responding.
+
+With the connection closed, the next stanza to be directed to that
+server will trigger Prosody to establish a new connection, instead of
+queueing it on the potentially broken connection.
+
+This should prevent messages from being stuck in a queue for a
+potentially long time before being bounced back to the sender as
+delivery failure reports.
+
+Normally the amount of time it takes for a broken connection to time out
+is determined by TCP.
+
+If this is deemed sensible behavior then it will likely be merged into
+Prosody itself somewhere.
