Actually I do not see the problem here. Only someone with the
capability to configure their smtp server to listen on another

which case, any spam they may send will go out with the source
as their smtp server

that 'source' being an IP address from the Orange allocation,
which comes to the same thing - the orange allocation getting
blacklisted.

Unless I misread Kyle's original post, he has smtp servers at his office or home most likely connected to some kind of permanent connection not GPRS on another network. Afterall having an smtp server on a dynamic ip is strange if it is meant to receive incoming mail as well. He was trying to connect to them and use them as his smtp servers from his orange GPRS connection. However ORANGE blocks outgoing smtp connections from their network unless you're connecting to their own servers that they have configured for this purpose. Kyle's workaround was to configure his servers to listen on a high port and thus he was able to use his servers as his outgoing smtp server rather than the orange servers.

Unless I misunderstood his setup, This should not be cause for alarm for the ORANGE team as the only ip address that would be blocked would be that of Kyle's smtp server which is most likely not even on their range in any case.
