Outside access to the GAE-powered XMPP bots
Origin: Enabling chat outside Google Apps
To use XMPP bots, deployed on Google AppEngine (thanks to the new AppEngine SDK 1.2.5) from non-Google XMPP accounts (jabber.org etc.), in the DNS records for your domain (example.com) add:
_xmpp-server._tcp.example.com. IN SRV 5 0 5269 xmpp-server.l.google.com. _xmpp-server._tcp.example.com. IN SRV 20 0 5269 xmpp-server1.l.google.com. _jabber._tcp.example.com. IN SRV 5 0 5269 xmpp-server.l.google.com. _jabber._tcp.example.com. IN SRV 20 0 5269 xmpp-server1.l.google.com.
