Error when MailScanner calls Sendmail

If 66.4.192.160 is the actual IP of your server - and you're not
running a local DNS - then it could just be that there's no DNS PTR
record for 66.4.192.160.

When I run: host 66.4.192.160

I get: Host 160.192.4.66.in-addr.arpa. not found: 2(SERVFAIL)

In this case, gethostbyaddr(66.4.192.160) is going to fail as well.

Perhaps the DNS PTR record for this host disappeared last friday? Or
something else in the DNS setup?
