Sending Multiple Mails per SMTP Connection
By default, a single SMTP transport creates a single connection and re-uses it
for the lifetime of the script execution. You may send multiple e-mails through
this SMTP connection. A RSET
command is issued before each delivery to ensure
the correct SMTP handshake is followed.
Examples
Sending Multiple Mails per SMTP Connection
use Zend\Mail\Message;
use Zend\Mail\Transport\Smtp;
// Create transport
$transport = new Smtp([
'host' => 'mail.example.com'
]);
// Create a base message:
$template = new Message();
$template->addFrom('sender@example.com', 'John Doe');
$template->addReplyTo('replyto@example.com', 'Jane Doe');
$template->setSubject('Demo of multiple mails per SMTP connection');
$template->setBody('... Your message here ...');
// Loop through recipients:
foreach ($recipients as $address) {
// Clone the message and add a recipient:
$message = clone $template;
$message->addTo($address);
$transport->send($message);
}
If you wish to have a separate connection for each mail delivery, you will need
to create and destroy your transport before and after each send()
method is
called.
Manipulating the transport between messages
You can manipulate the connection between each delivery by accessing the transport's protocol object.
use Zend\Mail\Message;
use Zend\Mail\Protocol\Smtp as SmtpProtocol;
use Zend\Mail\Transport\Smtp as SmtpTransport;
// Create transport
$transport = new SmtpTransport();
$protocol = new SmtpProtocol('mail.example.com');
$protocol->connect();
$protocol->helo('sender.example.com');
$transport->setConnection($protocol);
// Loop through messages
foreach ($recipients as $address) {
$mail = new Message();
$mail->addTo($address);
$mail->setFrom('studio@example.com', 'Test');
$mail->setSubject(
'Demonstration - Sending Multiple Mails per SMTP Connection'
);
$mail->setBodyText('...Your message here...');
// Manually control the connection
$protocol->rset();
$transport->send($message);
}
$protocol->quit();
$protocol->disconnect();
