 From Sendmail FAQ:

-->
Q3.38 -- What does "may be forged" mean?
Date: November 12, 2001

After sendmail does a hostname look-up on the IP address of the
connecting client, the IP addresses of that hostname are looked up. If
the client IP address does not appear in that list, then the may be
forged tag is added.
<--

Common mistake, especially among Microsoft techs. ;-)
