nit: "fix" doesn't tell me what was broken and what you improved about
it.  Here, I think you mean "respect transferencoding config option".

nit: I was confused when first reading this, since I read "the
configuration $target_xfer_encoding" as a single phrase.  A comma
after "configuration" might help.

run-on sentence.  I'm having trouble parsing this part.

Can you start from the beginning and describe again what this does?
In other words, tell me

- What is the user-facing effect of the change?  What workflow is it
  part of?

- Any risks or complications?

- Any technical details that might be interesting to the later reader?

- What does this allow me to do that I couldn't do before?

The code can speak for itself, so this should primarily focus on the
intention behind the change.

Makes sense.

Is there a way to cover this in tests (t/t9001-send-email.sh) so we
can avoid regressing again?

The rest looks good.

Thanks for noticing, and hope that helps,
