yes it does. yes it does. yes it does.

I did have had a .. relationship with both of these, too.
I think NetBSD's Mail(1) is the outstanding neat and clean one in
respect to conformance to these standards, at least still and as
of *today*, and to the best of my knowledge.

'From_' quoting has a terribly long story beside that, as many do
know, and many false solutions imho have been used or are still in
use even today; let's just mention the rather famous thread from
1996-05-17 [1].

Unfortunately POSIX and backward tools like Python's standard
library MBOX support go for a 'From_' quoting that can be dated
back to RFC 976 -- from February 1986!

The good thing about using quoted-printable encoding for 'From '
lines, instead of whatever MBOXO/MBOXRD etc. quoting, is, beside
being required for S/MIME (digest does not change since data
content is not modified, but only the transfer-encoding), that
even those backward-oriented and savage tools will work with
message content that is produced today, transparently.
