Postfix / PHP Mail（）以相同的电子邮件地址发送电子邮件，忽略标头$ from

Question

We recently upgraded our webserver and one of the first issues we came across was having problems sending to the same domain because the website was hosted on a different server to the company's exchange server. Anyway I fixed that it was some simple config changes and disabling the mail service for the domain.

Anyway, that's not working but what I didn't notice at the time when I was testing some PHP mail forms on the website was that they are all getting sent as my email address to the client.

This is the PHP (Which I don't think is a problem)

<?php
    ini_set("sendmail_from", "noreply@******.com"); 

    $name       = $_POST['name'];
    $email      = $_POST['email'];
    $phone      = $_POST['phone'];
    $comments   = $_POST['comments'];
    $ip=$_SERVER['REMOTE_ADDR'];

    $recipient  = '*****@******.com';
    $subject    = "Comments submitted from the Contact Us form on www.wavesfm.com from $name" ;

    $message   = "This is an email submitted from the Contact Us form on the website www.*****.com containing details from $name \n";
    $message  .= "    \n";
    $message  .= "Name: $name \n";
    $message  .= "Email: $email \n";
    $message  .= "Phone Number: $phone \n";
    $message  .= "Comments: $comments \n\n\n";
    $message  .= "IP Address: $ip ";

    $headers   = "From: noreply@********.com \n";
    $headers  .= "Reply-To: $email";

    mail($recipient,$subject,$message,$headers);
    header( 'Location: http://www.*****.com/thanks.php' ) ; 
?>

Can anyone see any issues with that code? I have tried adding -fnoreply@ * *.com as a send parameter but it wont change my own email address from appearing as the sender.

I don't think this is a PHP issue it seems more like a Postfix issue, but whats really bothering me is how my email address which isn't used anywhere is appearing as the sender.

Has anyone had experience with this before? as before 2 weeks ago I hadn't used Postfix at all so its all rather new to me.

Web Server: Cent OS, Plesk 11.0.9

Mail Server: MS Exchange Mail Server / Using ORF

Answer 1

There might be some string concatenation issues with the following code:

$headers = "From: noreply@********.com \n";

try

$headers = "From: noreply@********.com \r\n";

I recommend using phpmailer class for sending emails which is widely used: https://github.com/Synchro/PHPMailer

Answer 2

The php.ini sendmail_from directive only really applies on windows boxes

sendmail_from string Which "From:" mail address should be used in mail sent from PHP under Windows. This directive also sets the "Return-Path:" header.

I don't think it's a code issue as such. Which user are you running the webserver+php environment from on your Linux box? If you're running it as yourself then it's probably submitting to postfix using your email address.

Don't forget to tail /var/log/maillog if you're using postfix, that can tell you a lot and help you get to the bottom of the issue.

sudo tail -f /var/log/maillog

You could try signing up for a free account with Sendgrid and coupled with PHPMailer, Zend Mailer or Symfony Mailer libraries use that to send the emails and see if you get the same issue.
