Let me play dumb, because I don't understand the problem here.
It looks to me like dynamic 72.167.52.118 submitted mail to its smtp
server 64.202.189.102. Why is that bad?
My understanding is that his server _is_ 72.167.52.118. his From
indicates pousada.com.br:
$ host -t mx pousada.com.br
pousada.com.br mail is handled by 10 mail.pousada.com.br.
$ host mail.pousada.com.br
mail.pousada.com.br has address 72.167.52.118
so he has a generic rDNS:
$ host 72.167.52.118
118.52.167.72.in-addr.arpa domain name pointer
ip-72-167-52-118.ip.secureserver.net
and this will cause delivery problems nowadays.
In addition, his server helos with Pousada.com.br.secureserver.net which
does not resolve.
and
$ telnet 72.167.52.118 25
...
220 Pousada.com.br.secureserver.net ESMTP
so the hostname in the banner seems to be another one:
$ host Pousada.com.br.secureserver.net
Host Pousada.com.br.secureserver.net not found: 3(NXDOMAIN)
oops.
