spamc 3.1.0a-2 (i386 binary) in ubuntu dapper

Client for SpamAssassin spam filtering daemon
 spamc is the client to communicate with spamd, the daemonized form of
 SpamAssassin (see the spamassassin package). It is written in C for
 maximum speed and minimum loading overhead.
 .
 spamc is quite useful for integrating spamassassin into an MTA or
 into a .procmailrc file because of its speed.
 .
 This package is useless unless you have spamassassin installed,
 either on this machine or another local machine (i.e. a mail server).
