Hi All, It seems that we're having some problems receiving emails from selected Yahoo! Mail Accounts. I noticed that there is a commonality between the accounts that fails when sending an email to our domain (see email header below) From: "MAILER-DAEMON@nm1.bullet.mail.sg1.yahoo.com" <MAILER-DAEMON@nm1.bullet.mail.sg1.yahoo.com> To: *-*-*-*-*a@yahoo.com Sent: Fri, April 8, 2011 6:26:08 PM Subject: Failure Notice Sorry, we were unable to deliver your message to the following address. <xxxxxxxxxa@stluke.com.ph>: Mail server for "stluke.com.ph" unreachable for too long --- Below this line is a copy of the message.
