Fix yahoo smtp mail error code 554 Message not allowed PH01 not accepted for policy reasons

Blocked by yahoo smtp server

For some reasons, my mail server has been denied by yahoo smtp server, I can not send email to yahoo.com domain, the mail log is something like this :

B078B14A8008: to=someone@yahoo.com, relay=mta5.am0.yahoodns.net[66.196.118.34]:25, delay=2.9, delays=0.04/0/0.78/2.1, dsn=5.0.0, status=bounced (host mta5.am0.yahoodns.net[66.196.118.34] said: 554 Message not allowed - [PH01] Email not accepted for policy reasons. Please visit http://postmaster.yahoo.com/errors/postmaster-27.html [120] (in reply to end of DATA command))

I have tried changing my mail server using another IP but no luck. I also tried contacting with yahoo webmaster but no responses.
