This worked for me:
yum --enablerepo=rpmforge downgrade perl-Razor-Agent

rpmforge repo has new version of perl-Razor-Agent, you can try below command instead:

# yum update --enablerepo=rpmforge perl-Razor-Agent

Then try original command again:

# yum install --enablerepo=rpmforge razor-agents

Above is the error when I try to install the razor agent (CentOS 6.2). However, as I mentioned before, here is one example of a Razor2 hit:
Yes, score=19.407 tag=-9000 tag2=5 kill=15 tests=[HTML_IMAGE_ONLY_24=1.282, HTML_IMAGE_RATIO_02=0.805, HTML_MESSAGE=0.001, HTML_MIME_NO_HTML_TAG=0.635, HTML_SHORT_LINK_IMG_3=0.328, MIME_HTML_ONLY=1.105, RAZOR2_CF_RANGE_51_100=1, RAZOR2_CF_RANGE_E8_51_100=2, RAZOR2_CHECK=3, RCVD_IN_BRBL_LASTEXT=1.644, RDNS_NONE=1.274, TO_NO_BRKTS_DIRECT=2.457, TO_NO_BRKTS_NORDNS_HTML=0.001, URIBL_BLACK=1.775, URIBL_DBL_SPAM=1.7, URIBL_WS_SURBL=0.4] autolearn=spam

In addition I check for settings that usually do get set up, so not sure where razor2 comes in, perhaps it is now built into spamassasin by default:
[root@ ~]# grep razor /etc/mail/spamassassin/local.cf
[root@ ~]# ls -la /var/spool/amavisd/razor-agent.conf
ls: cannot access /var/spool/amavisd/razor-agent.conf: No such file or directory

Hi copart,

iRedMail doesn't install Razor2 explicitly, it could be installed automatically as a software dependence. So iRedMail doesn't configure it by default.

Any error message of failed package installation?

Re: Install Pyzor, Razor2 and DCC on your CentOS/RHEL iRedMail Server

2012-01-22T04:56:19Z

iRedMail 0.7.4 appears to have Razor2 already, I am seeing it in the SA headers. Trying to install Razor2 as the instructions say, fails on a perl dependency issue with the iRedmail repository.

Does it have DCC and Pyzor? Anybody have success?

Hi folks,

can this tutorial still be used ? any changes ? or I can just go ahead and install/configure it ?
i am asking because I saw that configuration tutorial was posted in 2009 ...

Thank You

Re: Install Pyzor, Razor2 and DCC on your CentOS/RHEL iRedMail Server

2010-10-03T17:02:05Z

Just a quick note... the configure line in step 4: Install DCC failed for me because I didn't have gcc (a compiler) installed.

You might want to add a line:

yum install gcc

To make sure gcc + dependents are installed.

Thanks for a great tutorial!

It do not need the iptable for INPUT. the server only can connect the other server's ports tcp2307 udp 6277 24441.
# DDC, Razor2. Pyzor
-A INPUT -p tcp --dport 2307 -j ACCEPT
-A INPUT -p udp -m multiport --dport 6277,24441 -j ACCEPT

I installed it successfully!!

I have added these line in /etc/sysconfig/iptables to open the ports

# DDC, Razor2. Pyzor
-A INPUT -p tcp --dport 2307 -j ACCEPT
-A INPUT -p udp -m multiport --dport 6277,24441 -j ACCEPT

Thank you so much

Install Pyzor, Razor2 and DCC on your CentOS/RHEL iRedMail Server

2009-12-11T07:52:14Z

==========
Related forum topic: Tutorial for installing Pyzor2, Razor, dcc on Debian/Ubuntu
==========

I've noticed we have a tutorial for installing Pyzor2 and Razor on a Debian based distribution but not CentOS/RHEL, so here it goes

Open the following ports on your firewall

DCC port 6277 UDP
Razor2 port 2307 TCP
Pyzor port 24441 UDP

1. Setup required repositories

DAG Wieers RPMforge has the razor-agents and perl-Razor-Agent packages

For i386:

# rpm -Uvh http://rpmforge.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

For x86_64:

# rpm -Uvh http://rpmforge.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

Atomic Rocket Turtle has the latest version of pyzor

# wget -q -O - http://www.atomicorp.com/installers/atomic.sh | sh

Note. If you wish to disable the atomic repository after using it, simply edit /etc/yum.repos.d/atomic.repo and change enabled = 1 to enable = 0 in [atomic] section

2. Install the packages

# yum install pyzor razor-agents

3. Perform the following

# chmod -R a+rX /usr/share/doc/pyzor-0.5.0 /usr/bin/pyzor /usr/bin/pyzord
# chmod -R a+rX /usr/lib/python2.4/site-packages/pyzor
# mkdir /var/spool/amavisd
# chown amavis:amavis /var/spool/amavisd
# su -m amavis -c 'pyzor --homedir /var/spool/amavisd discover'
# su -m amavis -c 'razor-admin -home=/var/spool/amavisd -create'
# su -m amavis -c 'razor-admin -home=/var/spool/amavisd -register'

4. Install DCC

# cd /tmp
# wget http://www.dcc-servers.net/dcc/source/dcc-dccproc.tar.Z
# tar xzvf dcc-dccproc.tar.Z
# cd dcc-dccproc-1.3.103
# ./configure --with-uid=amavis
# make
# make install
# chown -R amavis:amavis /var/dcc
# ln -s /var/dcc/libexec/dccifd /usr/local/bin/dccifd

Note. You can ignore the sendmail build error's you see when you run ./configure --with-uid=amavis

5. Modify Spamassassin

Add the following to /etc/mail/spamassassin/local.cf

# dcc
use_dcc 1
dcc_home /var/dcc
dcc_path /usr/local/bin/dccproc
dcc_timeout     10
add_header all  DCC _DCCB_: _DCCR_

# pyzor
use_pyzor 1
pyzor_path /usr/bin/pyzor

# razor
use_razor2 1
razor_config /var/spool/amavisd/razor-agent.conf

score RAZOR2_CHECK 2.500
score PYZOR_CHECK 2.500
score DCC_CHECK 4.000

Enable the DCC plugin in /etc/mail/spamassassin/v310.pre

# DCC - perform DCC message checks.
#
# DCC is disabled here because it is not open source.  See the DCC
# license for more details.
#
loadplugin Mail::SpamAssassin::Plugin::DCC

Check your Spamassassin configuration

# spamassassin --lint

It shouldn't show any errors.

6. Restart Amavid and test away

# service amavisd restart

testing commands

# spamassassin -t -D razor2 < /usr/share/doc/spamassassin-3.2.5/sample-spam.txt
# spamassassin -t -D pyzor < /usr/share/doc/spamassassin-3.2.5/sample-spam.txt
# cdcc info
