Basically, any option that is expanded, but you should use harmless one,
e.g.

fine_transport:
...
headers_add = ${lookup mysql {...} {}{}}

Probably because it's spelled envelope_to_add. But you shouldn't use
that one on the remote_smtp transport and you cannot even use it since
it's not expanded.

Yes, that would be really nice. And also for ACLs. Name could be
"expand", "do" or something like that.
