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.

This year's DebConf in Managua took Debian to a new part of the world which is too little visited by major Free Software events, allowing the project to reach out to new contributors and learn new perspectives, as well as to continue its hard work towards the next stable release of Debian.

The conference brought together around 200 attendees from 32 countries, and helped many people make their first steps in contributing to Debian, including a large number of enthusiastic new volunteers from countries in Central America.

98 talks were given, with highlights including:

* EFI boot methodology [1]
* XCP, OpenStack, Debian and the Cloud [2]
* FreedomBox Update [3]
* Beginners Spanish [4]
