However, it is also important to provide a "safe" default. Also,
people's intuitions differ. :-) It is deliberate that Exim will not
accept any recipients by default. You have to tell it which ones to
accept. Now, I'm no longer working on Exim, so the current maintainers
may choose to change if they want to, but I suspect they won't because
it would be a huge incompatible change. And, personally, I still think
the current default is correct.
