>Description:
On www.freebsd.org, there are handbook files that were left behind after
moves/renames.

For example, here are old versions still showing up in search engines:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/smtp-dialup.html
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/smtp-auth.html

The current versions are here:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/SMTP-Auth.html
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/SMTP-dialup.html

There may be more.

>How-To-Repeat:
	
>Fix:
The old files should be deleted, and the web server should be configured to
permanently redirect the old URLs to the new.

To prevent it from happening in the future, the doc build procedure will
need some adjustment, as per gjb's comment at
