Here's the value of DNS reverse lookup done correctly --
If the IP address above resolved to anything at all, the relaying host
could have complained, leaving a record in the headers like this (for
example):
X-Authentication-Warning: mlug.missouri.edu: Host
dc-mx05.cluster0.hsacorp.net [209.225.8.15] (may be forged) claimed to
be dc-mx05.cluster1.charter.net
Then we readily see that something may be wrong. But the relaying host
may not even care...
