ok,
jejeje
I just saw the problem to see the config postifx, for inclusion in the post, by default puts the protocols
inet_protocols = ipv4, ipv6
By having the server ip IPV6 in principal, it seems that Google gives preference to this if there is in the system, I have this protocol only IPV4 and now works correctly
inet_protocols = ipv4
Thanks for the help
regards
