Yeah -- Phil refuses to make changes like defaulting the header_sender
callout to using a _real_ reverse-path instead of the empty sender,
because it would change the behaviour for existing users. It's a pain at
times, but overall it makes sense. It means you can upgrade with a very
good expectation that nothing will break.

That reminds me -- Exim's SMTP callouts correctly use the null sender,
where I believe Postfix's do not. I've had to implement a workaround for
broken Postfix callouts for certain addresses which only ever _send_
mail and shouldn't receive it.
