How to send an email from a fake sender?

Question

PHP

I need to send one email from an address I don't have access to.
How can this be implemented in PHP, through a server or website.

Answer 1

You can just send via php mail function. But then the recipient will display "it is impossible to authenticate the sender."
In general, it's better not to do that :)

Answer 2

The From: header is easy to fake. But the email header data will still indicate which server the email went through. It will work for a lamyr, but not for a well-versed person, on the contrary, he will know that someone tried to forge a letter ...

Answer 3

I don't understand what I need... Maybe like this:
if( isset( $_COOKIE['token'] ) )
{
header( 'Refresh: 0; url=/profile.php' );
}
else{
}
But keep in mind that cookies are stored by the user and he can set them himself.

Answer 4

Something like this (after authorization, $_SESSION['token'] should get the desired value, and the browser should set cookies):
if ($_COOKIE['token']===$_SESSION['token']) .... .
