SpamAssassin Simple Application _unix Linux

Here we only talk about the simple application of SpamAssassin, using SpamAssassin's rule set to label spam as spam, and then using policy to automatically transfer messages with spam characters to the junk e-mail directory in client Outlook.

Refer to the article
Ccert chinese spam Filtering rule set
(http://www.ccert.edu.cn/spam/sa/Chinese_rules.htm)

Test environment: redhat9.0
Prerequisite: Already installed qmail, this article has built the environment is Qmail+vpopmail+igeus

1: Install SpamAssassin
Installation Method 1: Directly through the CPAN installation
PERL-MCPAN-E Shell
Install Mail::spamassassin

2: Compile and install yourself
Go to http://spamassassin.apache.org to download the latest version of the software

After decompression: # Perl makefile.pl
# make
# make Install

# for a spam and non-spam test
In SpamAssassin source files directory:
Spamassassin-t < Sample-spam.txt > Spamtest.txt
Less spamtest.txt
Spamassassin-t < Sample-nonspam.txt > Nospamtest.txt
Less nospamtest.txt
The Spamtest.txt file will contain the "*****spam*****" line in the topic section, but not in the Nospamtest.txt file.
(Default read/ETC/MAIL/SPAMASSASSIN/LOCAL.CF configuration.)

If you have an error during make, refer to this article to resolve the problem http://blog.5ilinux.com/archives/2005/07/spamassassin.html

The combination of 5:qmail and SpamAssassin

Compiling QMAIL-SPAMC in the SPAMC directory of SpamAssassin 3.x
# Cc-o-O QMAIL-SPAMC qmail-spamc.c
# install-m 755 Qmail-spamc/var/qmail/bin

# ln-s/var/qmail/bin/qmail-queue/usr/bin/qmail-queue

Edit/etc/tcp.smtp as follows
127.:allow,relayclient= ""
: allow,qmailqueue= "/VAR/QMAIL/BIN/QMAIL-SPAMC"

And then:
Tcprules tcp.smtp.cdb Tcp.smtp.tmp < TCP.SMTP

In the compiled directory SPAMD directory
MV REDHAT-RC-SCRIPT.SH/ETC/RC.D/INIT.D/SPAMD

Start SPAMD
/ETC/RC.D/INIT.D/SPAMD start

This spamassassin will automatically judge the spam according to the rule set, and put the spam messages that are considered potentially possible into the junk mail * * * * * * * * * * * * * * * * * *, at a glance, as for client Outlook how to set policy to automatically transfer spam, I don't need to say.
