I just tried 
     /bin/rm /tmp/map
     cdcc -h /tmp "new map; add your-server-name"
     dccproc -QCh /tmp -i msg0
with msg0 containing 
    From service@paypal.com  Fri Apr  8 15:14:07 2005
    Received:  ...

Your first server says the target count for that env_From checksum is 0
but your second says
    X-DCC-UofM-Metrics: calcite.rhyolite.com 1033; env_From=ok Body=0 Fuz1=0
	 env_From: afafa770 e849f7a4 f4bc5b93 d3ec0ab1      ok

That is strong evidence that the last time dbclean successfully parsed
the /var/dcc/whitelist including the included files on your second
server, it found a line like
    ok  env_From  service@paypal.com

Because the DCC server said that the target count for the
env_From checksum (0xafafa770 0xe849f7a4 0xf4bc5b93 0xd3ec0ab1) 
was the special value 0x00fffff1.
