How hard was that?

Change your e-mail address, get a new account. This spam question seems suspicious.

Your email server is not properly identifying itself when connecting.


You will need to contact your email administrator or service provider and have your Reverse DNS configured properly. When contacting the administrator, be sure to include your error message-it may include information that will be needed to resolve the issue.


Hope that helps!

The address you sending your mail to is disabled or do not exist, you cant do anything about it.

it may be a tecnical problem. check well and try again,

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 delivery error: dd This message is looping: it already has my X-Yahoo-Forwarded line. (#5.4.6) - mta1023.mail.sp2.yahoo.com (state 18). --

It could mean that, but check the email address and make sure that it is correct. Also, could your daughter have changed her email address or maybe her mailbox is full.

Post the exact return message you get, it will give me more info
