confessions of a newbie

[Charlie Shub]

I installed bogofilter about a month ago

then, 

per ---- http://www.bgl.nu/bogofilter/training2.html

	cd spam
	bogofilter -sv < spam-found
	Created directory /users/ludell/users/cdash/.bogofilter .
	# 102493 words, 418 messages

	cd ~/mail
	cat [a-hj-np-rt-w]* ia* ie* op* s[acioty]* | bogofilter -nv
	# 1373824 words, 4564 messages

and add to .procmail

	# filter mail through bogofilter, tagging it as spam and
	# updating the word lists

	:0fw
	| bogofilter -u -e -p

	# if bogofilter failed, return the mail to the queue, the MTA will
	# retry to deliver it later
	# 75 is the value for EX_TEMPFAIL in /usr/include/sysexits.h

	:0e
	{ EXITCODE=75 HOST }
	
	# file the mail to spam-bogofilter if it's spam.

	:0:
	* ^X-Bogosity: Yes, tests=bogofilter
	spam-bogofilter


Then i experimented a while and ended up making a single small change
in spam_cutoff
	#
	#       decreased to .90 4/25/02 by cdash
	#       decreased to .2550 5/1/02 by cdash
	#
	#spam_cutoff = 0.95
	#       
	spam_cutoff = 0.2550


Since may 1, i've had 4 false negatives
                      0 false positives
		      164 true positives

I think that's pretty good.
For the false negatives, I send them through bogofilter -Ns

that is absolutely close enough for me
I get about 1000 e-mails a month
