===== Requisits =====
==== Firsts remarks ====
  - By initial choice, user mail directories are composed like this : /data/vmail/domainname/username/
  - You must have a valid FQDN with the corresponding reverse DNS.
  - You must have SSL/TLS certificates.
  - 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
<code bash>
# for postfixadmin
export PFADBNAME="db_pfadmin"
export PFADBUSER="pfadmin"
export PFADBPW="PASS1_CHANGEME"

export PFARODBNAME="db_pfadmin"
export PFARODBUSER="pfa_ro"
export PFARODBPW="PASS2_CHANGEME"

export PFARWDBNAME="db_pfadmin"
export PFARWDBUSER="pfa_rw"
export PFARWDBPW="PASS3_CHANGEME"

export DEFAULT_MAIL_DOMAIN="<changeme>"
export MAIL_SERVER_HOSTNAME="<changeme>"
export MAIL_SERVER_FQDN="${MAIL_SERVER_HOSTNAME}.${DEFAULT_MAIL_DOMAIN}"
</code>

==== Begin safely ====
Server update and resolvconf installation :
<code bash>
apt-get update
apt-get upgrade
apt-get install resolvconf
</code>

==== Network interfaces :====
<code bash>vi /etc/network/interfaces</code>
Verify/add : "dns-nameservers 127.0.0.1 <DNS_R_1> <DNS_R_2>"

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

==== DNS cache ====
<code bash>
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
</code>

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

==== Network restart ====
<code bash>
/etc/init.d/networking stop ; /etc/init.d/networking start
</code>
Rq : if the FQDN was changed, restart the server.


==== mysql-server installation ====
<code bash>
apt-get install mysql-server
# New mysql superuser password : enter and keep safely somwhere (ex : keepass)
apt-get install dbconfig-common
</code>

===== postfixadmin / postfix / dovecot installation =====
==== DBs configuration ====
DBs and users creation for postfixadmin

==== postfixadmin installation ====
<code bash>
apt-get install postfixadmin
# auto reconfigure : apache2
# reconfigure postfixadmin with dbconfig-common ? yes
# DB server to use with postfixadmin : mysql
# DB admin password : enter mysql superadmin password
# choose to install the package maintainer configuration file

==== dovecot installation ====
<code bash>
apt-get install dovecot-mysql dovecot-sieve dovecot-imapd dovecot-lmtpd dovecot-managesieved

==== Apache initial configuration ====
see corresponding howto

==== postfixadmin configuration ====
<code bash>

</code>


** 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
<code bash>
tail -f /var/log/syslog &
service dovecot stop
service dovecot start
service postfix start
fg
</code>

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

Final verification (all the chain)
<code bash>
# 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
</code>
