Normally you don't need to run DCC as a service in order to use it within 
SpamAssassin.

That said, if you were going to run it as a service on anything but a very large 
network, you'd probably want to run dccifd, but you didn't install that 
component of DCC. This isn't really that big a deal, but does shave a few 
milliseconds off each DCC check.

If you had a very large network (> 100k  emails a day) you'd use dccd, but 
that's getting a bit more advanced. using dccd is usually done for bandwidth 
reasons. Floods are large, but above 100k emails/day the total bandwidth used by 
all the queries is larger than the floods.

Are you sure you opened udp 6277?

Does running cdcc RTT as root (which forces a retest of all the servers, where 
info does not) show anything different?
