Using the environment strikes me as the way to go.  With the
Bourne shell it's pretty easy to pass the variables in, but
getting the right values out of sendmail is another matter.  I'd
suggest changing

   A=sh -c $u

to

   A=sh -c 'ENVELOPE_FROM=$g ENVELOPE_TO=??? $u'

(untested)

I write ??? because I don't know how you'll get the envelope
recipient out of sendmail, assuming you want something other than
the name of the program that's being run.  The name of the
program is in $u, of course.
