qmail-inject is not an MTA and it does not speak SMTP.

If you pass a message to qmail-inject, you're telling it that you want it
to turn it into an RFC 822 message and then inject it into qmail's queue.

qmail-inject is a piece of an MUA, specifically the bit that takes
potentially unqualified and incomplete local mail and turns it into RFC
822 mail.  If you don't want your message to be canonicalized according to
the rules that it applies, don't pass it to qmail-inject.  qmail only does
message rewriting if you explicitly use the interface that is documented
to rewrite messages, namely qmail-inject.
