This is exactly the problem with jabber losing messages. There is no Ack
message which the client has send to the server to ack the received
messages. Therefore the Server relies on the Ack from TCP socket which is
given before the message is received at the client. this is not a reliable
message transport. which is not as worse in chat situations but it is
dramatically in instant messages.

See smtp and pop3, both are morer reliable.
