info about spam messages

[Tayfun ASKER]

hi,
   i've been trying to employ bogofilter as a system wide spam detection
tool.

i just installed and trained bogofilter as described in the
documentations. using /etc/procmailrc of our mail server, i made every
email coming to our systems pass through bogofilter and tagged as spam
or not.

we receive 100k+ emails daily. we try to reject spam messages at MTA
level as much as possible, that is, before they are passed to procmail.
we use sendmail's access list for this.  any message coming from a known
spam site rejected by sendmail. i would like to feed the access list
from the results of bogofilter.

My question : is it possible to obtain header information of spam
messages from bogofilter. when i call bogofilter as "bogofilter -l", it
adds a single line to the syetem log. but that single line does not
contain any useful information about tagged message.

thanks
