To decide which from address to use for replying, the CLI (and therefore
emacs ui) looks for primary and other email addresses in the
reply-to/from, to, cc, bcc, envelope-to, x-original-to, and finally
received headers, in this order, before falling back to just using
primary email.

If someone is interested (read: I'm too busy right now), and it's
desirable, it would be a one-liner to add delivered-to in the to_headers
array in guess_from_received_header() in notmuch-reply.c. Plus a few
dozen lines of test code. ;)
