BitMessage a Secure email Client and Server

Introduction

Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "non-content" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs.

SME Server - Email & Webmail Part 4

Domains structure and incorporation

This is perhaps the complicated part because it largely depends on the domain service provider you are with, what you want from your hosted domain services and what you actually get.

SME Server - Email & Webmail Part 3

You have now completed the most of he important parts in terms of Internet connection of the server, and what we need do now is test the server configuration so the possible problems we may come across are not compounded because you have failed to configure your server correctly or forgot the cardinal sin of pluging in the ethernet port to your router.

Here is what we check for at this stage.

SME Server - Email & Webmail Part 2

Configuration

We are now halfway through our Email Server build, after you have rebooted your server you will be asked a number of questions that relate to how the server is configured.

SME Server - Email & Webmail Part 1

Introduction

SME-Server - What is it, it is nothing short of brilliant! At it's core is the CentOS Linux system and if that puts you off then it shouldn't as SME Server is one of the easiest configurable email server money can't buy. Being Linux of course it's free SoSLUG has been using this email server without failure since at least 2008. The worst problem we have ever had is the upgrade and even that is pretty easy. First of all let me tell you what SME Server isn't, you can not just install this server and not think about security, for one thing SME Server won't let you, so planning is a must for this server build.

Upgrading Version 2 Thunderbird to Version 3

Introduction

If you have updated recently your version of Linux Distro in Ubuntu, Mint and others you might have hit on a couple of upgrade problems associated with the Thunderbird Version released with the distro. This howto covers the instructions needed to overcome these problems. At least one of the fixes is very simple the other is only slightly more complex.

Importing an Address Book

As a complete and utter novice to Linux one of the first things I found I needed was a working Address Book. My first attempt to import one was a total disaster, leaving field names and data all over the place.

Accordingly, this article explains, I hope, how to import into a Linux operated computer a backed up version of windows address book stored as a Comma separated values (csv) file on a flash memory stick.

The simple answer "Because I can" is probably premature at this stage. The main reasons I want to do it are principle and security.

As Paul points out in his page on encrytping e-mail [[How to Encrypt emails in Debian Etch 64 bit, PCLinucOS and Ubuntu Hardy Heron.]] plain e-mail is inherently insecure. It is sent in plain text through servers you do not control including your ISP's. However even if you encrypt your e-mails, as Paul suggests, an attacker who can monitor your internet connection can learn a great deal about you by studying who you send e-mails to and who you receive e-mails from. In security jargon this is called "Traffic Analysis".

This is a project to build a mail server. I will be using these pages to document my design as I go along. Hopefully it will end up as a Howto and also perhaps a tutorial on Linux and e-mail. Although I am building this project for myself, I would like it to become a group project.

Anyone suggesting improvements or pointing out errors or omissions will be welcome. There are many resources available to help in this project, I will be using as many as I can and will be acknowledging and, hopefully, building on them.

Introduction

Why use email encryption?

It's common knowledge that email is not a secure medium to use for communication, but almost everyone has turned a blind eye to that and many millions of messages are sent each day, that are wide open to interception. More recently, the UK government has published plans to create a massive database of every email sent through the UK Internet system and this has raised very serious questions about personal privacy.
