That is cool!

| wietse\ ven...@example.com
But that now makes me wonder, since quoted-pair is nowhere in
sight (outside of quoted-string and c(omment )content).

I fully and blindly trust it. I am not looking. Do not
misunderstand my personal struggle with IMF/5322 etc etc as tries
to discredit postfix or something. I sit in a very small corner
of the internet, it is only i collect bug and other patches as
they fly by here and there, or stumble over some statements i do
not fully parse, and anyway itch my head how *i* can deal best
with those; currently, for example, msg-id's, here mutt(1) commit
message quote(s)
It turns out some illegal message-id headers have neither angle
brackets nor even an '@' in them. So adopt a different approach.
...
Keep parsing inside angle brackets non-strict, because of the history
of trac tickets (1116, 1935, 3090) demonstrating message-ids with
spaces inside the angle brackets, double-'@'s, or even completely
missing '@'.
So that sh.t that happens. And eg RFC 5322 errata 3135, a bit
extended (please excuse the full paste)
// IETF RFC 5322 errata 3135 (latter three invalid it says)
{imf::err_content, imf::mode_none, 0, "\"\"@by", "", {0,}},
{imf::err_content, imf::mode_none, 0, "foo.\"\"@by", "", {0,}},
{imf::err_content, imf::mode_none, 0, "\"\".bar@by", "", {0,}},
{imf::err_content, imf::mode_none, 0, "foo.\"\".bar@by", "", {0,}},
{0, imf::mode_none, 1, "foo\"\"@by", "\0\0foo\0by\0", {0,}},
{0, imf::mode_none, 1, "\"\"bar@by", "\0\0bar\0by\0", {0,}},
{0, imf::mode_none, 1, "foo\"\"bar@by", "\0\0foobar\0by\0", {0,}},
{imf::err_content, imf::mode_none, 0, "<\"\"@by>", "", {0,}},
{imf::err_content, imf::mode_none, 0, "<foo.\"\"@by>", "", {0,}},
{imf::err_content, imf::mode_none, 0, "<\"\".bar@by>", "", {0,}},
{imf::err_content, imf::mode_none, 0, "<foo.\"\".bar@by>", "", {0,}},
{0, imf::mode_none, 1, "<foo\"\"@by>", "\0\0foo\0by\0", {0,}},
{0, imf::mode_none, 1, "<\"\"bar@by>", "\0\0bar\0by\0", {0,}},
{0, imf::mode_none, 1, "<foo\"\"bar@by>", "\0\0foobar\0by\0", {0,}},
// (adapt)
{imf::err_content, imf::mode_none, 0, "a.().b@by", "", {0,}},
{imf::err_content, imf::mode_none, 0, "<a.().b@by>", "", {0,}},
(it says invalid likely because obs- stuff is 'word *("." word))'
and that it is not, i see)
