  • getting Status 4.4.7 when sending email to Yahoo

    Hi,

    Running Exchange 2003 and sending/receiving email fine EXCEPT some of our users are unable to send email to some specific Yahoo account. The status code from our Exchange is 4.4.7 which basically says it cannot conncet to Yahoo smtp server.

    I suspect either Yahoo has some anti-spamming software...

    Any ideas? Many thanks in advance.

    Try to relay mail by uisng SMTP connector and the ISP mail servers. You may find out that your domain/ip belong to some black list etc.

      Thanks for your help. The problem is solved. We point all internet to send via ISP mail server (who is hosting our domain).

      Best regards.
