Good point. So I deleted the MAIN_FORCE_SENDER line from
exim4.conf.localmacros,
ran update-exim4.conf,
ran /etc/init.d/exim4 restart,
and then ran  exim -bP macros | grep MAIN_FORCE_SENDER
which now produced no output.
Then I ran mailx -r with the desired from address.

All this made absoultely no difference. Exim still rewrites the "From"
address.
(Actually, that bad MAIN_FORCE_SENDER line was inserted in a misguided
previous attempt to fix the problem.)
