Olá Alex, isso mesmo todos os ips são do google mas o problema esté
neste 74.125.25.27 que não tem configurado o dns reverso para o
dominio aspmx3.googlemail.com.

Outro detalhe é que estes ips são aleatórios e alternam entre os hosts.

1   aspmx.l.google.com   173.194.70.26 (no glue)
5   alt2.aspmx.l.google.com   74.125.25.26 (no glue)
10   aspmx2.googlemail.com   74.125.143.26 (no glue)
10   aspmx3.googlemail.com   74.125.141.26 (no glue)
5   alt1.aspmx.l.google.com   74.125.143.27 (no glue)
