It seems ok on my system linux stock 2.2.17 perl 5.8.6 dunno what other libs might make a difference.
i ran it like this: wget -O - http://mail.units.it/6474 |spamassassin -t -D
it scored thus:
X-Spam-Status: Yes, score=15.1 required=9.5 tests=BAYES_50,J_CHICKENPOX_26,
J_CHICKENPOX_31,J_CHICKENPOX_32,J_CHICKENPOX_53,J_CHICKENPOX_65,
J_CHICKENPOX_81,J_CHICKENPOX_93,MSGID_FROM_MTA_ID,NIGERIAN_BODY1,
NIGERIAN_BODY2,NIGERIAN_BODY3,NIGERIAN_BODY4,RISK_FREE,TO_EMPTY,
URG_BIZ,US_DOLLARS_3 autolearn=no version=3.0.2i didn't time it with a clock, but the last of the debug output from URIDNSBL might be of interest
debug: URIDNSBL: query for start.no took 14 seconds to look up (sbl.spamhaus.org.:201.0.159.195)
debug: URIDNSBL: queries completed: 11 started: 0
debug: URIDNSBL: queries active: at Tue Jan 18 21:11:33 2005
debug: done waiting for URIDNSBL lookups to complete
maybe you could try that on your system and see if it is the URIDNSBL queries that are taking so long.
also, try running it through spamassassin as opposed to spamc, this might let us know if the problem is with spamd using too many handles as Christian suggests.
good luck, keith.
