使用代理服務器從PHPMailer發送電子郵件IP地址

Question

我需要使用代理IP地址發送來自PHPMailer的電子郵件，我知道這樣做需要使用fsockopen函數，因此我可以連接到SMTP帳戶，知道如果我必須連接到代理服務器，我必須再次使用fsockopen函數。但在另一個fsockopen中使用它fsockopen是行不通的。

我有透明代理，不需要驗證。我需要將它發送到外部電子郵件服務提供商的遠程SMTP服務器。

我曾嘗試代碼：

<?php 

    //SMTP params 
    $server  = 'smtp.espdomain.com'; 
    $server_port = '25'; 
    $username = 'smtp_login'; 
    $password = 'smtp_pass'; 

    //Proxy 
    $proxy  = '1.1.1.1'; 
    $proxy_port = 1111; 

    //Open connection 
    $socket = fsockopen($proxy, $proxy_port); 

    //Send command to proxy 
    fputs($socket, "CONNECT $server:$server_port HTTP/1.0\r\nHost: $proxy\r\n\r\n"); 
    fgets($socket, 334); 

    //SMTP authorization 
    fputs($socket, "AUTH LOGIN\r\n"); 
    fgets($socket, 334); 

    fputs($socket, base64_encode($username)."\r\n"); 
    fgets($socket, 334); 

    fputs($socket, base64_encode($password)."\r\n"); 
    $output = fgets($socket, 235); 

    fputs($socket, "HELO $server \r\n"); 
    $output = fgets($socket, 515); 

?> 

而且它不工作，我不知道爲什麼？

socat命令可以幫助在這種情況下，或有任何解決方案或替代解決方案來實現？

Answer 1

我終於找到使用socat，請按照下列步驟操作的解決方案：

1. 首先，您需要安裝socat在服務器上，您可以簡單地使用以下命令：

   yum install socat 
   

2. 然後運行以下socat命令，將結合PROXY_IP:PORT與HOST_ESP:PORT：通過HOST_ESP:PORT

   socat TCP4-LISTEN:proxy_port,bind=proxy_IP,fork,su=nobody TCP4:host:port,bind=proxy_IP 
   

3. 然後，而不是做出發送到ESP的，你可以只讓使用PROXY_IP:PORT和socat將自動重定向到HOST_ESP:PORT使用輸出PROXY_IP:PORT。

希望這會有所幫助。

難道這不是your earlier question的重複嗎？我看不出有太多變化。

您沒有正確使用代理（您無法在套接字內執行套接字），但PHPMailer沒有任何特定的代理支持。如果它將在任何地方，我會看看在SMTPOptions設置屬性，但據我所知PHP只提供proxy support in HTTP streams，所以你可能是SOL。運行本地郵件服務器來傳遞而不是代理可能更容易。

你可以試試這個...

<?php 

// The mailman object is used for sending and receiving email. 
$mailman = new COM("Chilkat.MailMan2"); 

// Any string argument automatically begins the 30-day trial. 
$success = $mailman->UnlockComponent('30-day trial'); 
if ($success != true) { 
    print 'Component unlock failed' . "\n"; 
    exit; 
} 

// To connect through an HTTP proxy, set the HttpProxyHostname 
// and HttpProxyPort properties to the hostname (or IP address) 
// and port of the HTTP proxy. Typical port numbers used by 
// HTTP proxy servers are 3128 and 8080. 
$mailman->HttpProxyHostname = 'www.my-http-proxy.com'; 
$mailman->HttpProxyPort = 3128; 

// Important: Your HTTP proxy server must allow non-HTTP 
// traffic to pass. Otherwise this does not work. 

// Set the SMTP server. 
$mailman->SmtpHost = 'smtp.chilkatsoft.com'; 

// Set the SMTP login/password (if required) 
$mailman->SmtpUsername = 'myUsername'; 
$mailman->SmtpPassword = 'myPassword'; 

// Create a new email object 
$email = new COM("Chilkat.Email2"); 

$email->Subject = 'This is a test'; 
$email->Body = 'This is a test'; 
$email->From = 'Chilkat Support <support@chilkatsoft.com>'; 
$email->AddTo('Chilkat Admin','admin@chilkatsoft.com'); 

// Call SendEmail to connect to the SMTP server via the HTTP proxy and send. 
// The connection (i.e. session) to the SMTP server remains 
// open so that subsequent SendEmail calls may use the 
// same connection. 
$success = $mailman->SendEmail($email); 
if ($success != true) { 
    print $mailman->lastErrorText() . "\n"; 
    exit; 
} 

// Some SMTP servers do not actually send the email until 
// the connection is closed. In these cases, it is necessary to 
// call CloseSmtpConnection for the mail to be sent. 
// Most SMTP servers send the email immediately, and it is 
// not required to close the connection. We'll close it here 
// for the example: 
$success = $mailman->CloseSmtpConnection(); 
if ($success != true) { 
    print 'Connection to SMTP server not closed cleanly.' . "\n"; 
} 

print 'Mail Sent!' . "\n"; 
?>
