Hello Guillermo,
Your mail may have been blocked due to having invalid SPF records. I
see that you are publishing SPF records:
$ host -t txt villasana.com.mx
villasana.com.mx text "v=spf1 a mx include:irt.com.mx ~all"
$
The include syntax means that there are more spf records at irt.com.mx
$ host -t txt irt.com.mx
$
But as you can see, irt.com.mx does not publish spf records.
Thanks,
Erik
