I have 2 mail servers running.  Both of them had this message in the log file.  On the first server all of the messages showed dcc4.dcc-servers.net.  The first message came up at 09:20:17 CET.  The last message was at 09:38:08 CET. Overall there were 140 messages. 

here is the output of cdcc info on that machine:

The other machine the messages started to pop up at 09:16:05 CET and stoppped at 09:47:49 CET.  All of them pointing to dcc3.dcc-servers.net.  There were 165 messages in the log file.

cdcc info on this machine currently shows:

It sounds as if the database of one of the public DCC servers overflowed.

The messages should have stopped much sooner than 18 minutes as the client
code switched to a different server, unless there is a firewall or
other filter that makes only one of the public DCC servers available.  

What does `cdcc info` say on your system?
