DCC not working

[Gareth]

I installed DCC and have got to the stage where a debug shows that it is
able to query the servers :-

| grep dcc
[12550] dbg: dcc: network tests on, registering DCC

However I have left it overnight and in the 1000 or so emails I have
received in that time there has not been a single hit.

Any ideas what could be wrong?
