Miuul Customer Support

Hello. We have two types of emails operating in our system. 1. Emails sent from people's email addresses. 2. Emails sent by filling out a form on our website. The first type directly lands in Zendesk, but the emails from the second type do not appear in Zendesk. Both are observed in the _____@miuul.com email, but I can't see them in Zendesk. We have performed all the necessary checks, but couldn't solve the problem. Can you help?
