Morning @morag11

Thanks for coming back to the community.

I'd recommend running a virus/malware scan on your device and updating your password. Once you have done this and if you still have the same error, please send me a private message with a screenshot of the error message/non-delivery report and the email address affected and we will help you further.

Speak to you soon

Leanne.

Sender Domain Rejected (black listed by local policy)

This issue can report as server error 550. It typically arises where a user's email address has been abused for the purposes of sending spam emails. It has nothing to do with server settings etc.

This requires intervention by staff to determine the cause of the problem and to issue advice to check your system for viruses and malware. Only after your system(s) have been affirmed to be clean can the black listing be lifted. As a precaution, you should change the password on the affected email address.
