SMTPsock应用--用php发邮件

SMTPsock应用--用php发邮件

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 ( $fp, "MAIL FROM: <$from> " );
$output = fgets ( $fp, 2000 );

echo $output;

fputs ( $fp, "RCPT TO: <$to> " );
$output = fgets ( $fp, 2000 );

echo $output;

fputs($fp,"DATA ");
fputs($fp,"To: $to ");

fputs($fp,"From: $from ");
fputs($fp,"Subject: $subject ");
fputs($fp,"$message . ");
fputs($fp, "QUIT " );
}
}
fclose($fp);
}

$SERVER_NAME="127.0.0.1";
$from_domain="ws";
$to=" daiger@xifeng.com ";
$from=" wangsu@xifeng.com ";
$subject="test SMTP through PHP 中文";
$message="Send email via PHP smtp connectionsnnnothing happenesn 中文

send_email ( $to,$from,$subject,$message );
