How to hide set from mail on smtp php mail
When sending emails using PHP's mail()
function or a library like SwiftMailer, the Set-Cookie
header is sent by default. This can be a security risk if you're sending sensitive information, as it can be intercepted by an attacker.
To hide the Set-Cookie
header, you can use the following methods:
Method 1: Using PHP's mail()
function
You can use the extra_headers
parameter to specify custom headers. To hide the Set-Cookie
header, you can set an empty string for the Set-Cookie
header:
$headers = array(
'From' => '[email protected]',
'Subject' => 'Test Email',
'Set-Cookie' => '', // Set an empty string for the Set-Cookie header
);
mail('[email protected]', 'Test Email', 'Hello, world!', $headers);
Method 2: Using SwiftMailer
If you're using SwiftMailer, you can set the setCookie
property to false
when creating the message:
$message = Swift_Message::newInstance()
->setSubject('Test Email')
->setFrom('[email protected]')
->setTo('[email protected]')
->setBody('Hello, world!')
->setCookie(false); // Set setCookie to false
$transport = Swift_SmtpTransport::newInstance('smtp.example.com', 587);
$transport->setUsername('your-username');
$transport->setPassword('your-password');
$mailer = Swift_Mailer::newInstance($transport);
$mailer->send($message);
Method 3: Using PHPMailer
If you're using PHPMailer, you can set the SetCookie
property to false
when creating the message:
$mail = new PHPMailer();
$mail->setFrom('[email protected]');
$mail->addAddress('[email protected]');
$mail->Subject = 'Test Email';
$mail->Body = 'Hello, world!';
$mail->SetCookie = false; // Set SetCookie to false
$mail->Send();
By using one of these methods, you can hide the Set-Cookie
header and reduce the risk of sensitive information being intercepted.
