Problem for receiving mail from Locaweb

Hello,

We have one domain using Zoho Mail (competengenharia.com.br), but for 3 days we are not receiving e-mails from server on Locaweb (Brazil). Example, if we send e-mail from domain competengenharia.com or zorpe.net to our Zoho Mail, nothing was happend.
