Requisits

Firsts remarks

  1. By initial choice, user mail directories are composed like this : /data/vmail/domainname/username/
  2. You must have a valid FQDN with the corresponding reverse DNS.
  3. You must have SSL/TLS certificates.
  4. Postfix configuration here is not suited to high traffic servers (ISP), for this target, see : hash_queue_depth and http://www.postfix.org/TUNING_README.html

Variables

RQ : change the 3 usernames and their passwords, the mail domain and the server hostname

# for postfixadmin
export PFADBNAME="db_pfadmin"
export PFADBUSER="pfadmin"
export PFADBPW="PASS1_CHANGEME"
 
export PFARODBNAME="db_pfadmin"

Begin safely

Server update and resolvconf installation :

apt-get update
apt-get upgrade
apt-get install resolvconf

Network interfaces :

vi /etc/network/interfaces

Verify/add : “dns-nameservers 127.0.0.1 <DNS_R_1> <DNS_R_2>”

vi /etc/hosts
/etc/hosts
127.0.0.1	localhost
<IP publique>	<FQDN>	<HOSTNAME>

DNS cache

apt-get install bind9
cp -a /etc/bind/named.conf.local /etc/bind/named.conf.local_
sed -i "s/\/\/include \"\/etc\/bind\/zones\.rfc1918\"\;/include \"\/etc\/bind\/zones\.rfc1918\"\;/g" /etc/bind/named.conf.local
/etc/init.d/bind9 stop
/etc/init.d/bind9 start

IF NO IPV6 (RQ bug on jessie : https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=767798)

cp -a /etc/default/bind9 /etc/default/bind9_
sed -i "s/RESOLVCONF=no/RESOLVCONF=yes/g" /etc/default/bind9
sed -i "s/OPTIONS=\"-u bind\"/OPTIONS=\"-4 -u bind\"/g" /etc/default/bind9
/etc/init.d/bind9 stop
/etc/init.d/bind9 start
sleep 3
rndc flush

Network restart

/etc/init.d/networking stop ; /etc/init.d/networking start

Rq : if the FQDN was changed, restart the server.

postfixadmin configuration

Todo by hand :

  • RQ : if you need to use hook scripts, you have to configure a sudoer : “wwwrun ALL = (courier) NOPASSWD: /usr/local/bin/postfixadmin-mailbox-postcreation.sh”
  • go to postfixadmin web interface : http://fqdn/admin_pfa/setup.php
  • generate a new admin password, and keep it safely somewhere, click on “generate passwork hash”
  • the web interface proposes to modify the conf file : /etc/postfixadmin/config.inc.php - modify line : $CONF['setup_password'] = 'changeme';
  • the web interface proposes to create a new superadmin, do it and keep safely password somewhere
  • verify the installation by going to : http://fqdn/admin_pfa/

At the end...

Do by hand :

  • Edit /etc/postfix/main.cf and change certificates files paths
  • Edit /etc/dovecot/conf.d/10-ssl.conf and change certificates files paths
  • Edit /etc/dovecot/conf.d/15-lda.conf and /etc/dovecot/conf.d/20-lmtp.conf in order to change postmaster address

# (re)start services

tail -f /var/log/syslog &
service dovecot stop
service dovecot start
service postfix start
fg

Add www-data alias

echo "www-data: root" >> /etc/aliases
echo "root: admin_<MAIL_SERVER_FQDN>@<DEFAULT_MAIL_DOMAIN>" >> /etc/aliases
newaliases

Final verification (all the chain)

# stop mail services
for SERVICE_ in postfix dovecot ; do service $SERVICE_ stop; done
# start mail services
for SERVICE_ in dovecot postfix; do service $SERVICE_ start; done

Not included for the moment :
