    $mailFrom = "ValidMailbox@validdomain";
    $mailTo = "ValidToAddress";
    $mailSubject = "Useful Subject:  Here's my subject";
     
    $mailSignature = "\n\n--\n";
    $mailSignature .= "Your friendly Neighborhood web application.\n";
    $mailSignature .= "For help and other information, see http://yourwebapp/help\n";
    
    $mailBody ="blahblahblah\n";
    $mailBody .= $mailSignature;
    
    $mailHeader  = 'From: "'.$mailFrom.'" '."\r\n";
    $mailHeader .= "Reply-To: $mailFrom\r\n";
    $mailHeader .= "X-Mailer: ".MYSITE."\r\n";    
    $mailHeader .= "X-Sender-IP: {$_SERVER['REMOTE_ADDR']}\r\n";
    $mailHeader .= "Bcc: ".MONITORADDRESS."\r\n";	
    	
    $mailParams = "-f$mailFrom";
    $mailResult = mail($mailTo,$mailSubject,$mailBody,$mailHeader,$mailParams);


Be aware of this ''$mailParams = "-f$mailFrom";''

in ''php.ini'' there is **''sendmail_path''** with default settings (for *nix): ''sendmail -t -i''
