[Dovecot] dovecot director service

hi, we are using the dovecot-rc1 version, and we are testing the director service, as there is little documentation on this service, a pair of questions..

if i'm not wrong, the proxy_maybe it's not implemented, yet? will be soon? this limitation does not allow use the same two directors servers like mail backend servers? the fairlure of one director server it's automatically detected or require manual intervention?

thanks and sorry for so many questions...
