Use this (or a variation) when replying to email, such as sent to webmaster@fedoraproject.org, where the complaint is due to a Fedora-branded Apache test page. 

 
"The Fedora Project does not have anything to do with the
website you are having problems with.  You are probably seeing the
Fedora server test page:

https://fedoraproject.org/wiki/Server_Test_Page

Directly contact the owner or the Internet service provider (ISP) of
the server you are having problems with.  This can be done with a
Whois lookup:

Good luck."
