This guide is meant to build a spam and virus scanner to be put in place with an existing mail setup. All mail to the domain will come through this server, and then be relayed for normal delivery, with spam forwarded to [email protected]. This has been tested in front of Domino.
This doc is a collaboration from James and Derek at PCA (thanks guys), various docs at fedoranews.org, Ugo Bellavance, and my own experiences.
First things first, you need these software packages to continue:
Fedora Core 1 MailScanner Webmin Sendmail (should install with OS) SpamAssassin - do not install from Fedora, get the source tarball DCC Pyzor Razor Clam-AV
Fedora Core 1 Install
In the FC1 install, select ONLY Sendmail and Sendmail-cf under Mail Server, Development Tools, and Kernel Development. Nothing else is needed from Fedora.
Run yum update as soon as you're done booting upThis will ensure a fully up-to-date system to work with.
Before you begin, make sure you have the following packages installed:
http://www.webmin.com
I'm attempting to add/install MailScanner to my ubuntu 11.10 desktop configuration running postfix. I tried installing the latest 12.04 LTS but it had neither MailScanner nor qpopper package, 11.10 has qpopper so this is the release I went with. Development Tools - you'll need this to compile software. Install MailScanner: MailScanner installation is very easy to install. Very easy to install, however, you need to make sure you have the proper PERL modules installed. It uses the same elements, but it's mostly web managed through webmin.
Before you install webmin, install Net:SSLeay with:
rpm -ivh perl-Net-SSLeay-x.xx-x.rhfc1.dag.i386.rpm with the package specifically for FC1 put together by Dag Wieers. Once the install is complete, download webmin and install it with: rpm -ivh webmin-x.xxx-x.noarch.rpm Open up a web browser, and point to https://your-box:10000. Once you're logged into webmin, you can click on the system tab, and go to bootup/shutdown and turn off any unnecessary services, and stop them from starting up. Install MailScanner - http://www.sng.ecs.soton.ac.uk/mailscanner/downloads.shtml
There have been some posted problems with man2prod errors, to avoid this type:
LANG=C Unpack the tar file with: tar xvzf MailScanner-x.xx-x.tar.gz cd MailScanner-x.xx-x ./install.sh (You may need to run ./Update-MakeMaker.sh) Create Sendmail-cf Open up your favorite text editor and edit /etc/mail/sendmail.mc, and comment out the following lines by placing dnl in front of them: dnl DAEMON_OPTIONS('Port=smtp,Adr=127.0.0.1, Name=MTA') dnl FEATURE('accept_unresolvable_domains') dnl Close and save. Now recreate the sendmail.cf at a command prompt with: m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf Install SpamAssassin - http://www.spamassassin.org/downloads.html Get the following four rpms: spamassassin-x.xx-x.i386.rpm perl-Mail-SpamAssassin-x.xx-x.i386.rpm spamassassin-tools-x.xx-x.i386.rpm perl-Digest-SHA1-x.xx-x.i386.rpm Install all of these. That is it for now. Install DCC - http://www.dcc-servers.net/dcc/source/dcc-dccd.tar.Z Extract the package with tar zxvf dcc-dccd.tar.Z, cd into the directory, and to install type: ./configure; make install SpamAssassin will automagically pick up DCC and use it. Install Pyzor - http://pyzor.sourceforge.net You will need the package python-devel for Pyzor Extract the package with tar zxvf pyzor-0.4.0.tar.gz, cd into the directory, and to install type: python setup.py build python setup.py install Pyzor will automagically be picked up by SpamAssassin as well. Install Razor - http://razor.sourceforge.net Download the razor-agents, and the razor-agents-sdk tarballs, along with Net::DNS and Time::HiRes perl modules. Extract the razor-agents-sdk first with: tar zxvf razor-agents-sdk-2.03.tar.gz tar zxvf razor-agents-2.40.tar.gz cd into the agents-sdk directory first, and type: perl Makefile.PL make make test make install When you're done with both packages, type in: razor-client, which creates the needed symlinks. Razor will automagically be picked up by SpamAssassin. Make this a shell script, and chmod 744 it. I put it in /etc/cron.daily #!/bin/sh pyzor discover razor-admin -discover /var/dcc/libexec/updatedcc Install Clam-AV - http://www.clamav.net First, create the clamav user and group. groupadd clamav useradd -g clamav -s /bin/false -c 'Clam Antivirus' clamav Download clam-av, and extract it with: tar zxvf clamav-x.xx.tar.gz cd into the directory, and run: ./configure make make check make install MailScanner will update your Clam-AV defs for you. Configure MailScanner Modify the following in /etc/MailScanner/MailScanner.conf MTA = sendmail Use SpamAssassin = yes Delivery Method = queue Spam Actions = forward [email protected] High Scoring Spam Actions = forward [email protected] Virus Scanners = clamav Comment out the following lines in /etc/MailScanner/spam.lists.conf #MAPS-RBL blackholes.mail-abuse.org #MAPS-DUL dialups.mail-abuse.org #MAPS-RSS relays.mail-abuse.org #MAPS-RBL+ rbl-plus.mail-abuse.org *Note - make sure you make an account [email protected] Configure Sendmail From Webmin, click on Servers, click on Sendmail Configuration. Go to Domain Routing (mailertable) and manually edit /etc/mail/mailertable and add the following line: yourdomain.com esmtp:normalmailserver.xxx.com normalmailserver.xxx.com is the full hostname of the mail server that spam server will forward all mail to. Make sure to separate with the tab key and save the settings. Next, Click on Relay domains and add yourdomain.com
I certainly dont mind learning new skills. I wish I knew Linux better after working with it for over 10 years.My challenge is the same as for most of us, we have a lot of ground to cover. Various Windows server technologies, different NIX distros and the hardware. I would love to know more about all of them. I shove stuff in my brain and most leaks out.We have Webmin on all our Linux servers. Makes my work easier and reduces the learning curve.btw I tried to install Webmin 1.90 on EFA4 and failed.
