I cannot guarantee 6 nines of probability (but can guarantee as many eights
as one migh wish ;)

Socket buffering and timing might cause smtp dummy to be killed before
it has read all content...

But... i recall bash has a way to do tcp stuff .../dev/tcp/host/port
is mentioned in manual page.
I'll investigate this later (or, anyone of you, provide a patch :)
