To test if Spamassassin works with the new ruleset, run this command:

/home/admispconfig/ispconfig/tools/spamassassin/usr/bin/spamassassin –lint

If it does not return an error message, then Spamassassin is working correctly.

Error Opening file /usr/share/GeoIP/GeoIP.dat

The solution is to install the missing package manually:

apt-get install geoip-database

Edit the postfix main.cf file:

vi /etc/postfix/main.cf

and add the line:

smtp_bind_address = 192.168.0.1

were 192.168.0.1 has to be replaced with the primary IP address of the server. Then restart postfix:

/etc/init.d/postfix restart

Filesystem notification initialization error -- contact your mail
administrator (check for configuration errors with the FAM/Gamin library)

when I tried to access a IMAP share. The resaon for the problem seems to be that the “fam” package was not working correctly. The solution is to install the gamin package which can replace fam in a courier setup:

apt-get install gamin

Dont worry when you get a message from apt that libfam0 gets uninstalled but is required by courier. This had no geative effects on my server.

Installation

apt-get install libapache2-mod-evasive

Create the log directory for mod_evasive

mkdir -p /var/log/apache2/evasive
chown -R www-data:root /var/log/apache2/evasive

Now we add the configuration for the module at the end of the file /etc/apache2/mods-available/mod-evasive.load

vi /etc/apache2/mods-available/mod-evasive.load

so that it looks like this:

LoadModule evasive20_module /usr/lib/apache2/modules/mod_evasive20.so

DOSHashTableSize 3097
DOSPageCount 2
DOSSiteCount 50
DOSPageInterval 5
DOSSiteInterval 1
DOSBlockingPeriod 10
DOSLogDir “/var/log/apache2/evasive”

and restart apache:

/etc/init.d/apache2 restart

Edit the file /etc/php5/conf.d/xcache.ini

vi /etc/php5/conf.d/xcache.ini

and check the mm_path. On a OpenVZ virtual machine it should be set to “/tmp/xcache” as /dev/zero might not work correctly in a virtual machine:

xcache.mmap_path = “/tmp/xcache”

Then restart apache2:

/etc/init.d/apache2 restart

and check if the error has been resolved.

If the roor still occurs after some time, you will have to reduce the xcache.size.

Edite the xcache.ini file:

vi /etc/php5/conf.d/xcache.ini

and set xcache.size to e.g. 8 MB

xcache.size  =                8M

Then restart apache2:

/etc/init.d/apache2 restart

I will use VPSID as placeholder for the ID of the virtual machine in the commands and the script. Replace VPSID with the id of the virtual machine that you want to create the script for, e.g. replace VPSID with 101.

Create the script:

vi /etc/vz/conf/VPSID.mount

and insert the following lines:

#!/bin/bash
mount -n –bind -onosuid,noexec /vz/vps/VPSID/tmp /vz/root/VPSID/tmp
mount -n –bind -onosuid,noexec /vz/vps/VPSID/shm /vz/root/VPSID/dev/shm
exit ${?}

now make the sscript executable:

chmod 700 /etc/vz/conf/VPSID.mount

I used this to migrate a ISPConfig Debian system to OpenVZ successfully.

Download the latest Spamassassin sources and unpack the tar.gz file

cd /tmp
wget http://ftp.fernuni-hagen.de/ftp-dir/pub/mirrors/\
www.apache.org/spamassassin/source/Mail-SpamAssassin-3.3.1.tar.gz
tar xfz Mail-SpamAssassin-3.3.1.tar.gz

Configure, make and install spamassassin

cd Mail-SpamAssassin-3.3.1
perl Makefile.PL PREFIX=/home/admispconfig/ispconfig/tools/\
spamassassin/usr SYSCONFDIR=/home/admispconfig/ispconfig/\
tools/spamassassin/etc
make
make install

Cleanup

cd ..
rm -f Mail-SpamAssassin-3.3.1.tar.gz
rm -rf Mail-SpamAssassin-3.3.1

To enable port 587, edit the file /etc/postfix/master.cf

vi /etc/postfix/master.cf

and remove the # in front of the line:

#submission inet n – n – – smtpd

so that it looks like this:

submission inet n – n – – smtpd

and restart postfix:

/etc/init.d/postfix restart
