lately users in my domain are experiencing problems sending mail to yahoo users..the message appears to be sent from their inbox but it fails to get it delivered to users at yahoo...so I decided to check the queue details from admin
console...there I'm getting strange errors..listed below:
Code:
Mar  9 09:43:17 mail postfix/smtp[32123]: D0DC12A0B3C: host d.mx.mail.yahoo.com[66.196.82.7]
refused to talk to me: 421 4.7.1 [TS03] All messages from mydomain.com will be permanently
deferred; Retrying will NOT succeed. See http://postmaster.yahoo.com/421-ts03.html
is my server being black listed by yahoo...guys on the forum ..any help would be
greatly appreciated.
