server_name可以用php自己的dns解析函数,
以下是核心演示,winNT,mail server is Imail,php3.0.6
需要修改php3.ini打开imap模块,在linux上要编译php --with-IMAP
function send_email ( $to,$from,$subject,$message ){
global $SERVER_NAME;
$fp = fsockopen ( $SERVER_NAME, 25 );
if ( $fp ){
echo "connected";
set_socket_blocking( $fp, false );
$output=fgets($fp,2500);
echo $output;
if (! ereg ( "^220", $output ) ) {
exit();
} else {
echo "talking ";
//set_socket_blocking ( $fp, true );
fputs ( $fp, "HELO $from_domain
" );
$output = fgets ( $fp, 2000 );
echo $output;
fputs ( $fp, "MAIL FROM:
" );
$output = fgets ( $fp, 2000 );
echo $output;
fputs ( $fp, "RCPT TO:
" );
$output = fgets ( $fp, 2000 );
echo $output;
fputs($fp,"DATA
");
fputs($fp,"To: $to
");
