Many thanks.  That "-f ..." sound good.  When "rc8" appears I'll try my
best to test it as promptly as possible.


To other readers who helped on this thread (and to whom I'm grateful):

Timo says "Dovecot deliver is the one that needs to write the From_ line."
Indeed.  But that's subtly different from "[...] needs to generate [...]".

Dovecot needs to ensure that a "From_" line is written to the output mbox
file.  But the contents of that "From_" line should, ideally, represent
the envelope sender of the incoming email, and that information simply
isn't present, except in a "From_"-like field.  (The visible "From: "
isn't necessarily the same as the envelope-sender.)
