Another solution for PHP under Mail

Resolved a period of time before I contacted Dec Tru64 Unix i installed the Php+apache, you can use the mail function provided is always unable to send a letter, and then a function, it uses the pipeline under the Unix and PHP sock function to send letters, after the experiment is very successful in the The following is the original code for this function.
function MyMail ($mto, $MCC, $msubject, $mbody)
{
$from = "webmaster@backhome.com.cn";
$sign = "";/whatever you write.
$sendmailpath = "/usr/lib/sendmail";//semdmail path
$bound = "========_". Uniqid ("Bcfmail"). " ==_ ";//delimiters
$headers = "mime-version:1.0".
"Content-type:multipart/mixed; boundary= "$bound" ".
"Date:". Date ("D, D M h:i:s Y"). " ".
"From: $from".
"To: $mto".
"Cc: $MCC".
"Subject: $msubject".
"Status:".
"X-status:".
"X-mailer:my Email Interface".
"X-keywords:";
$content = "-$bound." "." content-type:text/plain;charset= "GB2312" ". $mbody. $sign." ";
$end = "". " --". $bound." -- ";
$sock = Popen ("$sendmailpath-t-F ' webmaster@backhome.com.cn '", ' w ');
Fputs ($sock, $headers);
Fputs ($sock, $content);
Fputs ($sock, $end);
Fputs ($sock, ".");
Fputs ($sock, "QUIT");
Pclose ($sock);
}
