This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database. This tutorial is based on Ubuntu 12.04.

An email gateway (a.k.a. firewall) is a machine (physical or virtual) installed between Internet and the email server. Its primary role is to protect the email server by filtering incoming messages, via SMTP protocol, from Internet. Secondary, an email gateway may be used as an outgoing gateway in case you want to add some new email features which are not provided by older email servers. For instance, Exchange 2000 or 2003 has no DKIM signing and verification service – a quality improvement for message delivery. This tutorial shows how to configure an email gateway with the Scrollout F1 email gateway.
