Is there an actual [email protected] email address? And (more importantly) is the brazilbr.com the domain name of your site? If not, then your hosting place will ignore the ‘from’ email when it processes the wp_mail() command.
You need to make sure that the ‘from’ email address you use in wp_mail() is an email address on the domain for your site. If needed, created an email account on your domain, then use forwarding rules to get it to the [email protected] email address.
You can also set the ‘reply-to’ in the mail header to whatever you want. But the sender email must match the domain of the site that is sending the mail. If not, the mail will get delivered, but will not have the ‘from’ address you specified. And, some mail clients might block your email as spam, since the sender email doesn’t match the sender domain.
