Forms arrives in spam

When I submit a form and the recipient has a Microsoft 365 account, the form ends up in their spam folder. According to the administrator of the mail server, this is the reason: The display name does not match the sending domain.

Essentially, Microsoft interprets this as phishing because my email address is used as the sender, even though I am not the actual sender.

Do you recognize this problem? Can you help me?
