Why run your own email server? Perhaps you have a website, which needs to send emails to users, or maybe you want to store your emails on your own server to protect your privacy. However, building your own email server can be a pain in the butt because there are so many software components you need to install and configure properly. To make this journey easy for you, I’m creating a tutorial series on how to build your own email server on Ubuntu.

I confess, I'm an outlaw at heart. I like using packet sniffers like tcpdump because it satisfies my base snooping impulses. Packet-sniffing is wiretapping after all, only it's applied to TCP/IP packets, not voice transmissions. Sure, they're my packets on my systems, but still the idea is appealing. Did you know that you can use tcpdump to verify that encryption on your POP email server is working? Find out how in this informative tutorial from Carla Schroder.

Do you use Windows? Do you want to use GnuPG? Are you new to GnuPG in a windows environment? Then look no further! This document was written for new users who have never installed or used GnuPG before and have not perhaps done any reading but just wish to "dive right in and get started" using signing and encryption. If this is the case, please take your time to read through the whole document first skipping the update instructions (which make up significant portions of the document now). Be sure that you are comfortable with all the terms etc. before doing anything!
