I'm no smail expert but here goes. There is an smail mailing list
which you should find useful:
smail3-users@cs.athabascau.ca

Use the rewriting rules as in your 2nd question and included and
variable you like with the prefix "$".

I believe the "From: " is required by IETF standards.

Not sure on this one. "From: " is always required. The others are
optional. For example, pine will prompt the user if "Return-path: "
is defined in the message if they would prefer to use that instead of
"From: ".
