The problem, Dave, is NOT sites messing up the "From " line, but rather
Berkeley Mail uses the "From: " line in preference to it (since "From: "
complies with RFC822, and "From " does not).  Non sendmail sites which
don't update "From: " cause it to become incorrect.  I posted a hack to
Berkeley Mail for this a few weeks ago, if anyone still has it online.
If not, I can resurrect it.
