Hi! I recognized that IDLE was not working as expected on our murder setup. We've two frontends, 3 backends and a dedicated mupdate server, all running 2.3.13. idled is active on the backends.
I did some strace'ing on front- and backends and as far as I can tell, the frontends do not proxy the IDLE command to the backends, because the frontends think the backends are not CAPAable to do IDLE. I searched the source and it seems that there is a problem with the capability check the frontends do on the backends. On one hand cyrus announces CAPABILITY in the greeting banner. But CAPA_PREAUTH doesn't contain all of the caps the frontend wants to know. eg. IDLE, MULTIAPPEND, RIGHTS and LIST-SUBSCRIBED. On the other hand, the frontend is told by the protocol definition in imap_proxy.c:107, that it should exclusively check the banner in backend.c:400 for the CAPS, which doesn't contain the needed info in pre_auth state. Am I right, that either capa_response(CAPA_PREAUTH); should return the needed caps for the frontends, too, or the frontends should'nt believe blindly in the banner capabilites?
