Here is something I knocked up quickly.
Installing separate Web and Email server with ISPCP Control Panel.
Firstly I have built 2 identical servers in VMWare, all have 512MB RAM, 40GB Harddisks and have a fresh install of Debian Etch from the Netinst CD. The servers have an internet connection during the build.
The partitions are set up as follows though you can alter these to suit:
100MB - /boot
2GB - /
768MB – SWAP
768MB – SWAP
2GB - /tmp
1GB - /var/log
Remainder - /var
At package selection I de-selected all options.
The servers are called:
web.testdom.co.uk
email.testdom.co.uk
Web has the IP address of 192.168.1.1
Email has the IP address of 192.168.1.2
As this is a test run, this guide is a “quick and dirty” way to test the concept. Please feel free to offer feedback or edit this document.
Once all servers have Debian installed, login as root and type:
apt-get install ssh
This will allow us to ssh into the servers and this will allow an easier install. (i.e. you can copy and paste).
Once ssh is installed, exit and ssh into the 3 servers.
Add the following lines to /etc/apt/sources on all 3 servers.
deb
http://ftp.de.debian.org/debian/ stable main contrib non-free
deb
http://security.debian.org/ stable/updates main contrib non-free
Run the following on all 3 servers.
apt-get update && apt-get upgrade
(If the kernel updates be sure to reboot before continuing).
Run the following on the web server:
apt-get install apache2 apache2-mpm-worker apache2.2-common apache2-utils bind9 bzip2 diff dnsutils gcc gzip iptables libapache2-mod-fastcgi libberkeleydb-perl libc6-dev libcrypt-blowfish-perl libcrypt-cbc-perl libcrypt-passwdmd5-perl libdate-calc-perl libdate-manip-perl libdbd-mysql-perl libdbi-perl libio-stringy-perl libmail-sendmail-perl libmailtools-perl libmcrypt4 libmd5-perl libmime-perl libnet-dns-perl libnet-netmask-perl libnet-perl libnet-smtp-server-perl libperl5.8 libsasl2 libsasl2-modules libsnmp-session-perl libterm-readkey-perl libterm-readpassword-perl libtimedate-perl libmysqlclient15off make mysql-client original-awk patch perl perl-base perl-modules php4 php4-cgi php4-gd php4-mcrypt php4-mysql php4-pear php5-cgi php5-gd php5-imap php5-mcrypt php5-mhash php5-mysql proftpd-mysql rkhunter sasl2-bin ssh tar wget bash libnet-libidn-perl nfs-common postfix courier-base rkhunter mysql-common mysql-server
Run the following on the mail server:

Firstly we focus on the Mail Server
Edit /etc/exports
Add lines:
/etc/courier 192.168.1.1(rw,no_root_squash)
/etc/postfix 192.168.1.1(rw,no_root_squash)
/var/mail 192.168.1.1(rw,no_root_squash)
Edit /etc/hosts.allow
Add lines:
portmap: 192.168.1.1
lockd: 192.168.1.1
rquotad: 192.168.1.1
mountd: 192.168.1.1
statd: 192.168.1.1
Edit /etc/hosts.deny
Add lines:
portmap:ALL
lockd:ALL
mountd:ALL
rquotad:ALL
statd:ALL
Run:
/etc/init.d/portmap restart
/etc/init.d/nfs-common restart
/etc/init.d/nfs-kernel-server restart
(Expect some errors in ref to subtree_check)
Now we focus on the web server
edit /etc/fstab
Add lines:
192.168.1.2:/var/mail /var/mail nfs rw 0 0
192.168.1.2:/etc/courier /etc/courier nfs rw 0 0
192.168.1.2:/etc/postfix /etc/postfix nfs rw 0 0
Run mount -a
Download ISPCP.
Enter the directory with the ISPCP files and
make install
cp -Rv /tmp/ispcp-1.0.0/* /
cd /var/www/ispcp/engine/setup
mysqladmin -u root password WHATEVERYOUWANTTHEPASSWORDTOBE
perl ispcp-setup
Enter the required details, note that when asked .
Now we need to reconfigure Squirrelmail
Edit file /var/www/ispcp/gui/tools/webmail/config/config.php
Locate line $smtpServerAddress = 'localhost';
Replace localhost with mail server ip
Locate line $imapServerAddress = 'localhost';
Replace localhost with mail server ip
Back on the mail server.
Edit /etc/postfix/main.cf
Change entries myhostname and mydomain to show email server name
run /etc/init.d/postfix restart
Job done.
When rebooting/powering on the servers, make sure the mail server comes up first before powering up the web server.
Reason for edit - I removed the mysql bits as it still doesnt work on a separate server.
