From 30bcbf775abbf8582a6fac2ac1b23a220508ea62 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Mon, 3 Apr 2017 15:58:07 +0100 Subject: Accept join events from all servers Make sure that we accept join events from any server, rather than just the origin server, to make the federation join dance work correctly.
