Hi
emails sent from our server to yahoo user's are constantly bounced back. we have submitted their "Bulk Sender Form" many times but didnt get any response from yahoo and our mails are still bouncing. Here is the SMTP error:
 OutboundConnectionResponse SMTPSVC1 SERVERNAME - 25 - - 421+4.7.0+[TS02]+Messages+from+xxxipAddress+temporarily+deferred+due+to+user+complaints+-+4.16.56.2;+see+http://postmaster.yahoo.com/421-ts02.html 0 0 145 0 1500 SMTP - - - -

There specific solution is listed here:

I would suspect that if you don't get a response within an acceptable period of time, maybe you should look into routing email via an alternative SMTP host.

It is possible that users are continuing to block your messages by marking messages as spam within their webmail clients?
