I made this script for myself but it could be useful for you too. If you like the Howtoforge.com's "The Perfect Server - Ubuntu 14.04 (Apache2, PHP, MySQL, PureFTPD, BIND, Dovecot, ISPConfig 3)" build, you can install/config that in minutes:

1. install a fresh Ubuntu 14.04 server
2. wget http://merlinw.org/data/install.sh
3. chmod +x install.sh
4. sudo ./install.sh
5. Follow the instructions

The script installs apache2, pure-ftpd, quota, clamav, postfix, mailman, dovecot,
