Does this mean that the existing method of installing MailScanner (i.e. going to mailscanner.info / downloading the installer for MailScanner) is going away?

* What is it?
This is a new Yum repository for CentOS 5 i386 and x86_64 only. It will
always contain the latest MailScanner beta (4.72.2 at the time of
writing) along with SpamAssassin (plus DCC, Razor, DKIM, SPF, IP-Country
and Rule2XS plug-ins), ClamAV and all Perl module dependencies.
It should be used for beta testing new releases only and should not be
used in production.
* Why is it different from other repositories?
Because it aims to completely eliminate the problem of package conflicts
and to make installations and upgrades as simple as possible. These rpms
provide an automatic configuration that contains the regular tuning tips
that would be unfamiliar to those who do not have in-depth knowledge of
MailScanner and it's configuration. This significantly reduces the
amount of time it takes to do an installation. From start to finish, the
installation and configuration of all packages takes less than five
minutes on a reasonably fast network.
Package conflicts are avoided by creating a new RPM namespace for all
the Perl modules required by MailScanner and SpamAssassin and by
installing all Perl modules (except SpamAssassin) in
/opt/fsl/lib/perl5. This allows the Perl system libraries to be totally
independent so they can be updated by the operating system vendor
without the possibility of breaking MailScanner or SpamAssassin.
Automatic configuration is achieved by using RPM 'triggers' which allow
the installation, upgrade or un-installation of one package trigger to
access an action specified by another package. For example - when
're2c' is installed, the fsl-spamassassin package runs a trigger that
automatically runs 'sa-update' and 'sa-compile' to get the latest rules
and compile them and then automatically enables the 'Rule2XSBody'
plug-in in v320.pre, subsequently if 're2c' is uninstalled, then the
plug-in is automatically disabled.
* Installation procedure
Ideally it should be installed onto a server with a fresh minimal
installation of CentOS/RHEL 5. This will allow the operating system and
all MailScanner related applications to be safely updated by simply
running `yum -y update`.
If you want the MailScanner package to automatically mount the
MailScanner incoming directory on tmpfs then run the following command
before starting the installation:
Then simply run:
wget http://yum.fslupdate.com/fsl-beta/fsl-beta.repo -O
yum -y groupinstall MailScannerGold
Once all the packages are installed, the only configuration required is
to MailScanner.conf, Sendmail (/etc/mail/access, /etc/mail/mailertable)
and then enable and start them both by running:
chkconfig MailScanner on
service MailScanner start
* Installing over an existing RPM based installation
This is no different to the procedure above - except you should back-up
your MailScanner and SpamAssassin configuration first as a precaution.
The 'stock' MailScanner package has no automatic upgrade procedure you
will need to manually run upgrade_MailScanner_conf and/or
upgrade_languages_conf if any rpmnew files are created by the new package.
Sign-up for the fsl-beta support list at
The use of the repository is entirely unsupported by FSL, so use is at
your own risk - however we will be happy to answer and questions about
the repository or packages on the fsl-beta list.
* MailScannerGold PRODUCTION
The MailScannerGold Production yum repository will be available in a few
days. We'll post another announcement when it's available for
subscription and downloading.
Initial pricing for the production version subscription is a monthly fee
of $30 / month for the first gateway and $20 / per month for each
additional gateway. This should help us to recover our costs for
development and maintenance while at the same time costing sites less
that the salaries required for administrators to fully maintain and
update the MailScanner systems.
Support for MailScannerGold PRODUCTION will provided by a subscribers
supported and FSL moderated email list. Subscribers to the service will
also be able to obtain FSL support services at our standard hourly rates
less a 25% discount.
These repositories should make installing, running and updating
MailScanner a lot easier for both newbes and experienced mail
