I'm using 5.0.7_GA_2444.RHEL4.... Installation went fine. In order to forward all soap requests to a different host, I changed the zimbra.soap.url parameter. This seemed to work fine in the Standard version, but didn't make any difference in the Advanced (AJAX) UI.
Any ideas? If it's not possible to configure zimbra to forward soap requests to a different host, does anybody know how to configure Jetty to forward (or proxy) /service/soap requests to another server?
