Hello,

Thank you for contacting Yahoo! Customer Care.

We appreciate your report as your input helps us to identify ways to
constantly maintain and improve our service. We apologize for any
inconvenience this has caused you. If you notice any further
difficulties when delivering to Yahoo! Mail accounts, after waiting a
reasonable amount of time, please let us know by replying directly to
this email. However please note the following:

If you are receiving the error code "421 Message from x.x.x.x
temporarily deferred" or "451 Message temporarily deferred - 4.16.50" in
your SMTP logs, this indicates that the message you attempted to send
was not accepted by Yahoo! Mail servers. It is not a permanent error;
your system will automatically re-try later. If, after attempting to
deliver to Yahoo! and receive the 4.16.50 error repeatedly and conform
to the best sending practices outlined in the following page, we
encourage you to apply for prioritized sending at the link below.

Recommended Best Practices:

   http://help.yahoo.com/help/us/mail/defer/defer-01.html

Prioritized Delivery (Please note that this form can also be used by
senders whose mailings are being directed to the Bulk Folder):

   http://add.yahoo.com/fast/help/us/mail/cgi_bulkmail

If you are receiving a separate error than that above, please provide
the text of any error messages you may have received. Also, providing
the specific IP address of the mail server that experienced the delivery
issue will help us to troubleshoot the issue more efficiently.

We appreciate your patience while we work to improve and maintain our
service.

Thank you again for contacting Yahoo! Customer Care.

Regards,

Samuel Cyprian

请问你是怎么修改DNS的,能说详细点吗,

tdk

我的问题解决了，修改dns后 421问题消失
看来还是mx A记录问题

tdk

我也是出现421问题，
我的邮件服务器在防火墙内，而且做了地址转换
不知道是不是和dns关系最大

还再找问题。

Franklin

各位，请帮忙，我也出现了这种情况，yahoo与hotmail的邮件都发不出去，但是可以收到，急啊！谢谢
