Zend_Mail provides generalized functionality to compose and send both text and MIME-compliant multipart e-mail messages. Mail can be sent with Zend_Mail via the default Zend_Mail_Transport_Sendmail transport or via Zend_Mail_Transport_Smtp.

$mail = new Zend_Mail();
$mail->setBodyText('This is the text of the mail.');
$mail->setFrom('somebody@example.com', 'Some Sender');
$mail->addTo('somebody_else@example.com', 'Some Recipient');
$mail->setSubject('TestSubject');
$mail->send();

Note: Minimum definitions
In order to send an e-mail with Zend_Mail you have to specify at least one recipient, a sender (e.g., with setFrom()), and a message body (text and/or HTML).

For most mail attributes there are "get" methods to read the information stored in the mail object. For further details, please refer to the API documentation. A special one is getRecipients(). It returns an array with all recipient e-mail addresses that were added prior to the method call.

For security reasons, Zend_Mail filters all header fields to prevent header injection with newline (\n) characters. Double quotation is changed to single quotation and angle brackets to square brackets in the name of sender and recipients. If the marks are in email address, the marks will be removed.

You also can use most methods of the Zend_Mail object with a convenient fluent interface.

$mail = new Zend_Mail();
$mail->setBodyText('This is the text of the mail.')
    ->setFrom('somebody@example.com', 'Some Sender')
    ->addTo('somebody_else@example.com', 'Some Recipient')
    ->setSubject('TestSubject')
    ->send();

The default transport for a Zend_Mail instance is Zend_Mail_Transport_Sendmail. It is essentially a wrapper to the PHP » mail() function. If you wish to pass additional parameters to the » mail() function, simply create a new transport instance and pass your parameters to the constructor. The new transport instance can then act as the default Zend_Mail transport, or it can be passed to the send() method of Zend_Mail.

$tr = new Zend_Mail_Transport_Sendmail('-freturn_to_me@example.com');
Zend_Mail::setDefaultTransport($tr);

$mail = new Zend_Mail();
$mail->setBodyText('This is the text of the mail.');
$mail->setFrom('somebody@example.com', 'Some Sender');
$mail->addTo('somebody_else@example.com', 'Some Recipient');
$mail->setSubject('TestSubject');
$mail->send();

Note: Safe mode restrictions
The optional additional parameters will be cause the » mail() function to fail if PHP is running in safe mode.
