(sorry for the major delay)

Argh, that's correct. We don't have anything in libcurl before this that
needs that feature.

I wonder how large percentage of use cases this will work for anyway. Lots of
machines today that speak SMTP will not be able to resolve their own names.

Is it really worth persuing or should we work on better documenting how a
client should do to provide the full host name itself?
