hostname -f hostname: Name or service not known

I'm pretty burnt on trying to figure this one out. The main problem is that when i use a loop with php mailer to blast email our users, it only gets to some, and I believe this to be a DNS issue.

Here is the mail code

function massEmail($from,$subject,$to,$body) {
    require_once('packages/class.phpmailer.php');
    $success = 0;
    foreach($to as $person) {
        usleep(2000);
        $mail = new PHPMailer(); 
        $mail->From = $from;
        $mail->IsHTML(true);
        $mail->FromName = "cmiVFX";
        $mail->Subject = $subject; 
        $mail->Body = $body;
        $mail->AddAddress($person);
        $ret = $mail->Send();
        if($ret) {
            $success++;
        }
    }   
    var_dump($success);
}

When running hostname I get this

server.cmivfx.com

When running hostname -f or --fqdn i get

hostname: Name or service not known

when restarting sendmail i get

hostname: Name or service not known

Here is my hosts file

127.0.0.1 localhost.localdomain localhost
127.0.1.1 server.cmivfx.com cmivfx.com
69.162.76.226 server.cmivfx.com cmivfx.com

my hostname file is

server.cmivfx.com

My mail servers point to google apps so dig cmivfx.com any gives me

And finally, when i run the mail php code with my gmail its fine. With some others I get

Could not instantiate mail function

Hopefully I've provided enough information that someone who knows about sendmail can help me out. Thanks so much!

There's conflict between /etc/hosts and /etc/hostname: change /etc/hostname as: cmivfx.com

If there's special reason you need remain hostname as server.cmivfx.com, you may use /etc/hostname + /etc/resolv.conf let 'hostname -f' to get the right FQDN.

You may get some background information here: configure FQDN on multiple domains supports mail server
