前一段时间我接触到DEC Tru64 Unix 我在上面装了php+APACHE,可以用提供的mail函数始终不能正常发信，于是自编了一个函数，它利用UNIX下的管道和PHP的SOCK函数进行发信，经过实验非常驻成功，下面是此函数原代码。
function mymail($mto,$mcc,$msubject,$mbody)
{  
$from="[email protected]";
$sign = "\n";//随你便写些什么
$sendmailpath="/usr/lib/sendmail";//Semdmail路径
$bound = "========_".uniqid("BCFMail")."==_";//分界符
  $headers =  "MIME-Version: 1.0\n".
            "Content-Type: multipart/mixed; boundary=\"$bound\"\n".
            "Date: ".date("D, d M H:i:s Y ")."\n".
            "From: $from\n".
            "To: $mto\n".
            "Cc: $mcc\n".
            "Subject: $msubject\n".
            "Status: \n".
            "X-Status:\n".
            "X-Mailer: MY Email Interface\n".
            "X-KeyWords:\n\n";
  $content="--".$bound."\n"."Content-Type:text/plain;charset=\"GB2312\"\n\n".$mbody.$sign."\n";
  $end = "\n"."--".$bound."--\n";
  $sock = popen("$sendmailpath -t -f '[email protected]'",'w');
  fputs($sock, $headers);
  fputs($sock, $content);
  fputs($sock, $end);
  fputs($sock, ".\n");
  fputs($sock, "QUIT\n");
  pclose($sock);
}
