Inability to send mails to yahoo.com domain

Hi guys,

For some reasons I cannot send mails to some domains, I get an error message 
saying;

There was a SMTP communication problem with the recipient's email server.  
Please contact your system administrator.
            <ewn-lges007.econet-nigeria.com #5.5.0 smtp;552 Put ,E=\r\n at the 
end of Mether, Mtcp, or Msmtp in sendmail.cf if you are using Solaris 2.5 
(fixed in 2.5.1). I cannot accept messages with stray newlines.  Many SMTP 
servers will time out waiting for \r\n.\r\n.>

I cant seem to understand why I get these messages. Could anyone please help on 
a resolution to this problem.


Thanks
