nail -- Nail is a MIME aware mailx replacement aka Heirloom mailx<hr>
<a href="http://heirloom.sourceforge.net/mailx.html">http://heirloom.sourceforge.net/mailx.html</a><hr>
nail is derived from Berkeley Mail. It got its name because the m
and n keys are located next to one another on the keyboard, and the
resulting word was easy to remember. Since version 10, nail also features
independent implementations of the System V and POSIX mailx additions.
It was named back to mailx in a Heirloom mailx, in early 2006
