Client IP address

[useopenid]

Additional information: I caught it in the act, and something about this
trigger and the setup is causing nginx to loop - the client ip address is
actually right and nginx is proxying the request to itself as fast as it
can.  Restarting nginx stops the loop.  This is version 0.7.65.  I tried
upgrading to 1.7.4 recently but the syslog support doesn't seem to work for
mail and I haven't gotten a chance to try the old patches yet.
