The message is baked into ancient versions of Cygwin.
I believe the page the auto-responder points them to
indicates the fact that their version is old and should
be updated.  This often happens because someone bundled
Cygwin with something else and is not updating the
Cygwin version.

Modern versions no longer generate the message.

In sum, the auto-responder is the best thing we can do
about it.  At least we don't have to have a human respond.
