I need some help working out why my postfix 2.10.1 is removing the sender

Postfix does not do that.

That logging is irrelevant. Don't needlessly enable verbose logging.
When postfix tries to send the email to the upstream smarthost, it's rejected
as it has a null sender (I've confirmed this with a network trace). I am
wondering what I should check next to nail the problem.
You're probably observing the transmission of a bounce, not the original
message.
Your upstream gateway should not reject relaying of bounces. If that
can't be fixed, find a better gateway.
