Why mailx doesn’t do Windows
Gunnar Ritter, maintainer of the commonly-used mailx program,
explains why it’s not available on Windows. It’s an interesting tale
of how the kluges deep within that semi-operating psuedo-system mean
that even in 2010 design decisions made in the Seventies afflict
Windows.
They afflict Unix too, of course, but generally our design mistakes were smarter than Windows’s design mistakes. Even in error we’re better.
