I have yum installed system-switch-mail but how do I use it, I can find no man page for it?
Entering 'system-switch-mail' in a shell displays a pop-up saying 'Unknown Error'.
Should I pass any command-line options?
The command-line way to do this is simply to use:
alternatives --config mta
You don't need any of the GUI stuff to do it that way.
