I believe you that a bug was fixed, I don't know enough exim to comment on that.

However, it seems to me that when a mail is sent to a local user, it is not a 
very sensible thing to do to forward it to the smart host as is, since it will 
surely fail. Shouldn't the default configuration do it differently?

Do you want mails to local users to fail?

This is important, because security checks, apt-changelogs, and surely other 
things are sent to a local user (root) by default.

Cheers,
