Nói ngắn ngọn, đây là do yahoo chặn IP của server, có thể do Yahoo nghi ngờ sevver này gửi spam mail….

Xử lý như sau:


vào trang: http://help.yahoo.com/l/us/yahoo/mai...ter/defer.html

Điều các thông tin của bạn vào,
riêng ở phần:
- About the problem: bạn chọn là: Getting deferrals due to user complaints (quan trọng)
– IP Addresses:: bạn điền IP của host/server mail vào (quan trọng)
(không không biết IP, bạn vào menu Start->Run-> gõ CMD -> gõ Ping mail.domain_của_bạn)
- Enter the full text of the error code(s) your mail server received from Yahoo!: Bạn copy nội dung lỗi trả về ở trên vào.
Các ô còn lại nhập cái gì vào cũng được.
Xong thì bấm Submit.



Thông thường IP sẽ được nhả ra trong 5-20 phút, bạn có thể thử gửi mail lại xem kết quả.

Bài viết rất hay và bổ ít!
