mtaproxy308.free.mail.gq1.yahoo.com has rejected your message to the following mail addresses :
[email protected] ([email protected])
We were unable to deliver your message. When Office 365 tried to send the message, the external mail server returned the following error. This is probably due to a problem or policy setting on the recipient’s mail system.
See the error for more information about the problem. It can tell you what happened and how to solve the problem. For example, if it indicates that the message was blocked due to a potential virus, try to send the message without attachments.
For mail administrators
This error was reported by a mail server outside of Office 365. If the sender cannot resolve the problem by modifying his message, it is probably a problem that only the recipient’s mail administrator can solve.
See the error for more information about the problem. The error may indicate the cause of the problem and provide guidance on how to resolve the problem. For example, if it indicates that the message was rejected due to a problem with the Sender Policy Framework (SPF) standard, you should work with your domain registrar to properly configure your SPF record.
See the error for more information about where the problem occurs. For example, search for a domain name such as contoso.com. This indicates the organization causing the error. The recipient’s mail server may be the source of the problem, or the problem may originate from a third-party service used by your organization or the recipient’s organization to process or filter mail.
If you cannot resolve the problem, contact the mail administrator of the responsible party. This may be the recipient’s mail administrator, the administrator of your active host service, and so on. Provide him/her with the error code and error message included in this delivery failure notification to help resolve the problem.
Office 365 Support cannot help you with this type of externally reported error.
