1. Make sure that all required packages for Exim to build successfully are installed. The minimal package requirements are the basic suite of compiler tools and basic libraries. You will also need to install the ccache package.
2. Create the master exim user (i.e. the user that Exim changes uid to when it runs in normal operation). I suggest the user **exim**. If you already have the Exim package provided by your distro installed, chances are good that you already have a user named **exim** or **exim4**. That user is fine. This howto also assumes you use the groupname **exim**.
3. Create a user that will run the Build Farm. I suggest the user **farm**. Due to some assumptions that are made in the test suite, the group name must also be **farm**. It is ok if you make it a secondary group or the primary group.
-4. Add **exim** as a secondary group to the **farm** user.
+4. Add **exim** as a secondary group to the **farm** user. (You should **NOT** add **farm** as a secondary group to the exim user; this will cause test errors.)
5. Configure sudo to allow user **farm** to elevate to root without a password. Run `visudo` and add:
`farm ALL=(ALL) NOPASSWD: ALL`
6. Change to the **farm** user.
