The mailserver project which I have been working on for many months now is getting to the point where it will soon be taking over the role of hosting all my email. No problems have been discovered over the past month and my upgrade script to regenerate the security certificates worked perfectly. A recent update to Dovecot, the IMAP system, means that a little more testing is in order due to modifications made to the config files.
When I finally release my documentation for the process it will outline the working setup at that time. No point in releasing something out of date.
