Problems with Outlook / @Terra

Hello, good morning!

Recently, a specific client of our company stopped receiving our emails. We have already checked the administrator panel and the emails are listed as "Delivered". We enabled the "Delivery confirmation" option in the emails to test, and it returns saying the following: Delivery to these recipients or group was completed, but the destination server did not send a delivery notification. This message returned when we sent an email to another client who also uses another provider "@openvia.com.br", but after checking, they found our emails in the spam box.

The client's provider is @terra.com.br.
