Email received says sender is not trusted

[Karlie]

Has anyone else found some emails in the junk mailbox that say the sender is not trusted, what does this mean?

[Michael Fry1]

It means that their domain may not be listed in the trusted domains list. You can use * to trust all domains.

Thanks, that property is set to our company email. However some customer emails go through but some do not.

Try adding the customer(s) domain and see if they get through.
