My mistake.  I should know better.  I got frustrated after
I couldn't get all the info I /know/ is in the mailbox.

The 'envelope' I wanted is referred to in libmutt as the
ENVELOPE structure, which contains the headers, but lacks
'Received:'.

Duly noted.

This is what caused the confusion:  Balsa has a view->all headers,
but it only adds some headers, not all.  I particular it doesn't
show Received: which /is/ in the mailbox.

This, and the added confusion that in libmutt/mutt.h, there is an
ENVELOPE structure.

Again, I apologize.
