In this part we will be adding to the mail server created in Installing A Mailserver on Ubuntu 14.04 LTS Part 1, in this part we will be building on that and adding anti-virus and anti-spam software and a tool to greylist emails to cut down on the work our server has to do. This will be added to postfix via amavis-new.
The server called mailserver will end up running the following servers and services. Once all the parts of this series posts are completed.
I wrote this HOWTO as record of what I did to get my own mail server up and running. I can now and in the future follow these steps again and rebuild my own mail server. I hope it is of use to others too.
Samba 4 is a good bit of software. If only that last few tweaks could be done to finish it and the documentation off it would be great software. I have found lot of ways to set up Samba4 as a AD DC most of which fail to work only this one series of steps worked. Samba4 configuration is really really flaky! The official Samba documentation is getting better and beginning to cover some of the configuration pitfalls.
For this how to we are building on some of my other howtos.
In this part we will connect a Linux machine to the domain and then login with users configured with Active Directory. Therefore domain users will always have the same UID and GIDs regardless of the machine they log into.
