It's not a question of practicality, but of the meaning of words.  The
word "illegal" means against some law or other.  There are no laws being
broken in this case - it's just a matter of the result of using such
addresses not being what you want, which is important in its own way.
That's all.

Smail 3.1 is unrelated to smail 2.n - it's a whole new package, and it
does everything sendmail does, only without all the complexity.  There
are many happy users of Smail 3.1 all over the world.
