Hi, After viewing the whole case log that you posted, I found this issue was related to the opposite configuration on the security rather than blacklist domain issue. I suggest we do a confirmation with the owner of the mail292c9.megamailservers.com, check whether any security delivery restriction has been configured on their email system that causes the email was denied from your domain. If the domain has been applied with the Sender Filtering or your domain was recognized as blacklist by their email system, the outcome is the same with the issue that you encountered. Thanks Allen
