    If it's only Yahoo not recieving the messages then it's unlikely that mail() is the culprit. I also don't think it'd be DNS-related otherwise it should never have worked (unless someone else made the change such as your host). My best guess is that it's Yahoo having flagged your domain for spam - only you know what you were sending. ;)

    Probably should be in the Site & Server-administration section but you'll probably get your answers here too.

    Thanks. i will post same thread there..

    i have dedicated server. so i can manage my own WHM.
    i've read somewhere that told if we configured rDNS, they can track where this mail origin. This make me take full responsible for what i sending. i can live with that.

    So yahoo suggest me to configure rDNS properly and other thing like opt-out, opt-in and bounces email.

    I made all what their suggest except for rDNS. dunno what to do. :confused:

    rDNS refers to the Reverse DNS - what name the IP address resolves to. This has to be done with the hosting provider level.

    To setup rDNS on your IPs, you need to contact your dedicated server provider and ask them to setup rDNS.
    Here's an example:
    Let's say your mail IP is: 55.555.55.555 and your domain name is mydomain.com

    You need to create an A entry in your DNS configuration (you can use your control panel for this) like:
    mail A 55.555.55.555

    Then you contact the hosting provider and ask them to setup rDNS for the IP 55.555.55.555 like:
    mail.mydomain.com
