Dear Zoho Support Team,

I am currently experiencing an issue when trying to send emails from my Zoho Mail account.

Each time I attempt to send a message, I receive the following error:

"Unable to send message; Reason: 554 5.1.8 Email Outgoing Blocked."

The email address affected is:

DOMAIN: pierrot.gr.jp

Could you please let me know why outgoing emails have been blocked and what steps I need to take to restore full sending functionality?

This account is used for official copyright communications, so resolving this issue is very important.

I would appreciate your prompt assistance.

Best regards,

Marjorie Kouma
