If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/exim
%  sudo port install exim  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching exim
--->  Verifying checksum for exim
--->  Extracting exim
--->  Configuring exim
--->  Building exim with target all

--->  Staging exim into destroot

--->  Installing exim

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using exim with these commands:

%  man exim
%  apropos exim
%  which exim
%  locate exim
