Hello,
Thank you for writing to Yahoo! Mail. We would appreciate it if you could
provide more information to help us troubleshoot the issue. Please note
that if you are not the system administrator for the mail server(s)
affected, we encourage you to contact the administrator so they can address
the possible issues regarding mailings from the mail server. Please reply
to this email with the following information:
* Explain the details of one event with the delivery problems to Yahoo!
Mail. Please provide the entire message, including the full text of the
error message returned, and full header information. Within a Yahoo! Mail
account, you can display this information by clicking the "Full
Headers" link located within the message in the bottom right-hand
corner.
* The specific server_domain name and IP address of the email server(s)
that have the delivery issue to Yahoo! Mail. IP Address: xxx.xxx.xxx.xxx
Mail Server Domain Name: server_name.domain.com
* Log messages from your mail server showing which IP you connected to
and what responses you got from the remote server at the time you received
the corresponding failures/timeouts for the event you are reporting.
* The results from a plain text message, sent to Yahoo! Mail, without
HTML, links, graphics or attachments, from the server having delivery
issues. Is the email delivered to Yahoo! Inbox? We appreciate your
assistance. This information will be helpful in determining the reason why
you are having issues when delivering mail to Yahoo! Mail accounts.
I await your response so I may resolve your issue. Thank you again for
