Instalarea unui server de email pe o mașină cu sistem de operare Linux (Armbian):

sudo aptitude update
sudo aptitude safe-upgrade
sudo aptitude install apache2 apache2-doc
sudo aptitude install mysql-server php5-mysql
sudo aptitude  install postfix
sudo service postfix restart
sudo aptitude  install dovecot-imapd dovecot-pop3d
sudo service dovecot restart
sudo aptitude  install squirrelmail
sudo squirrelmail-configure
sudo cp /etc/squirrelmail/apache.conf /etc/apache2/sites-available/squirrelmail.conf
sudo a2ensite squirrelmail.conf
sudo useradd myusername1
sudo passwd myusername1
sudo mkdir -p /var/www/html/myusername
usermod -m -d /var/www/html/myusername myusername
sudo chown -R myusername1:myusername1 /var/www/html/myusername1

Dacă am adăugat comenzile de mai sus intr-un fisier sh, rezultă o singură comandă:

./php_apache_mysql_postfix_email.sh

Success!
