php, send email from any email address [closed]

Answer 1

Basically, you set your mail headers which are containing, who is sending that email address. Fortunately, this mostly will arrive as spam (keywords: SPF, DNS PTR, ...)

Easiest thing would be to create classes for every account you are going to use (gmail, yahoo, ...) and then use the factory pattern to keep your code clean.

Best option would be: Use smtp with authentication. This is the most supported standard and you only have to code solutions for services that don't provide smtp auth.

UPDATE

I don't know how to help you. You want to send mails from every domain, without them being flagged as spam, just by providing a "mail from (enter email address here)" input field, and a full-magic-do-it-everything-script-package. But without having an idea of how mailing works.

Pro tip: read about SMTP and get an idea of how sending mails is working.

Answer 2

Sending email without authentication

<?php
$to      = 'nobody@whateverdomain.com';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: webmaster@whateverdomain.com' . "\r\n" .
    'Reply-To: webmaster@whateverdomain.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);
?>

The correct way of sending email is through a SMTP connection. Assuming the PEAR Mail package is installed.

<?php
 require_once "Mail.php";

 $from = "Name Surname <sender@yourdomain.com>";
 $to = "Name Whatever <recipient@example.com>";
 $subject = "Subject!";
 $body = "Hi,\n\nHow are you?";

 $host = "mail.yourdomain.com";
 $username = "smtp_username";
 $password = "smtp_password";

 $headers = array ('From' => $from,
   'To' => $to,
   'Subject' => $subject);
 $smtp = Mail::factory('smtp',
   array ('host' => $host,
     'auth' => true,
     'username' => $username,
     'password' => $password));

 $mail = $smtp->send($to, $headers, $body);

 if (PEAR::isError($mail)) {
   echo("<p>" . $mail->getMessage() . "</p>");
  } else {
   echo("<p>Message successfully sent!</p>");
  }
 ?>

Assuming you have Zend Framework, you can do the same by sending through Zend_Mail over SMTP. The example below uses information on Google SMTP

require_once 'Zend/Loader/Autoloader.php'; //Should be in the include_path
$autoloader = Zend_Loader_Autoloader::getInstance();

$config = array('ssl' => 'tls', 'port' => 587, 'auth' => 'login', 'username' => 'username@gmail.com', 'password' => 'password');
$transport = new Zend_Mail_Transport_Smtp('smtp.gmail.com', $config);

$mail = new Zend_Mail();
if (strtolower($this->getType()) == 'html')
$mail->setBodyHtml($this->getBody());
}
else {
$mail->setBodyText($this->getBody());
}

$mail
->setFrom($this->getFromEmail(), $this->getFromName())
->addTo($this->getToEmail(), $this->getToName())
->setSubject($this->getSubject());

$mail->send($transport);
