After looking through the install documentation for courier-authlib more
closely, I noticed that it if MySql is installed on the system, then the
MySql authentication module will automatically be built and installed.
However, we are running MySql on a different server than the one on which
I've installed Courier. Is there a way to build/install Courier with MySql
support when MySql isn't actually installed on the server that Courier is
being installed on?
