Timo, please check and approve. This was diff'd on 2.1.10 on my test 
server (2.1.9 and 2.1.10 at least had this callback issue).

*** lmtp-proxy.c-orig   2012-09-28 20:17:36.138916678 +0000
--- lmtp-proxy.c        2012-09-28 20:18:12.241940780 +0000

                 lmtp_client_send(conn->client, conn->data_input);
                 lmtp_client_send_more(conn->client);
         }
+       lmtp_proxy_try_finish(proxy);
   }

ie, call lmtp_proxy_try_finish once. If all is bad, this will wrap us 
up. If we have valid proxies, it'll probably not finish and we'll return 
to waiting on callbacks. I'm not sure of any blocking restrictions. I 
just know it works.
