PocketSOAP TCP Trace is such a tiny tool, that simply shows the readable content. Enough for me as I only want to forward the traffic.

Qmail tries to put outgoing mail into a local queue, but fails for the the user is not present. The error log shows something similar:

The solve the problem, the list of local domains in the virtual server have to be emptied. It should be found at /var/qmail/control/locals

Overwrite the file with empty input:
echo "" > /var/qmail/control/locals

More information on how to administrate qmail are written down at http://www.lifewithqmail.org

Stephen Cocks explains it the following way:

If you using async request/reply interactions via a reference/import, then
you must have a callback destination defined. The callback queue must be
exclusive (you can’t use the same queue for any other purpose).

The callback destination is used by the system to store context information,
keyed by message ID / correlation ID, so that the context can be restored
before a
response (received on the Response destination) is passed to the nominated
component (callback object). It’s basically part of the system and most
often you should just let the system create and manage it. You don’t need to
put messages on it. Like any queue it may need administrative attention from
time-to-time.

The receive (reply) destination is where the response to the service
invocation should be returned.
