Sendmail: sending emails to Yahoo problem
I've had this really strange problem that I've been scratching my head for a couple of weeks.
Whenever I send an email to yahoo with sendmail I get this error:
"Deferred: Name server: g.mx.mail.yahoo.com.: host name lookup failure"
My BIND DNS is setup correctly, emails sent to any other domain are working, just yahoo isn't working. I can use telnet from my server to send to yahoo and it works, only through sendmail it doesn't work, I also have mailscanner installed, the server is Centos 4.4
