Besides email, there is another important use for
reverse DNS that hasn't been discussed.  When
generating an SSL certificate for https traffic, you
need to put the name of your server into the
certificate request.  Then, when users access your
site, the reverse DNS entry is compared against this
name in the certificate (and in the URL) and if they
don't match, a warning is presented to the user.
