This was actually reported quite a while back and I thought had been "fixed"
(meaning the change put into the latest) but apparently it has not.
The problem is that the original sendmail.cf has the following:
#O SmtpGreetingMessage=$j Sendmail; $b
for the greeting message which is the primary interface name of the box.
It should have the following:
O SmtpGreetingMessage=$?{if_name}${if_name}$|$j$. Sendmail Ready; $b
which helos (greets) as the interface name that it was called on.
Change that line in your /etc/mail/sendmail.cf file and it will helo correctly
and will not fail the dnsreports tests.
