TYPO3 v7 has reached its end-of-life November 30th, 2018 and is not maintained by the community anymore. Looking for a stable version? Use the version switch on the top left.

There is no further ELTS support. It is recommended that you upgrade your project and use a supported version of TYPO3.

Mail API

Since version 4.5 TYPO3 CMS provides a RFC compliant mailing solution, based on SwiftMailer.


Several settings are available in the Install Tool ("All Configuration") affecting the sending process. The most important one is $GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'], which can take the following values:


$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'] = 'mail';

Default and backwards compatible setting. This is the most unreliable option. If you are serious about sending mails, consider using "smtp" or "sendmail".


$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'] = 'smtp';

Sends messages over SMTP. It can deal with encryption and authentication. Works exactly the same on Windows, Unix and MacOS. Requires a mail server and the following additional settings:

$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_smtp_server'] = '<server:port>';

Mailserver name and port to connect to. Port defaults to "25".

$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_smtp_encrypt'] = '<transport protocol>';

Connect to the server using the specified transport protocol. Requires openssl library. Usually available: ssl, sslv2, sslv3, tls. Check stream_get_transports().

$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_smtp_username] = '<username>';

If your SMTP server requires authentication, the username.

$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_smtp_password] = '<password>';

If your SMTP server requires authentication, the password.


$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'] = 'smtp';
$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_smtp_server'] = 'localhost';
$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_smtp_encrypt'] = 'ssl'; // ssl, sslv3, tls
$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_smtp_username'] = 'johndoe';
$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_smtp_password'] = 'cooLSecret';


$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'] = 'sendmail';

Sends messages by communicating with a locally installed MTA - such as sendmail. This may require setting the additional option:

$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_sendmail_command'] = '<command>';

The command to call to send a mail locally. The default works on most modern UNIX based mail servers (sendmail, postfix, exim).


$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'] = 'sendmail';
$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_sendmail_command'] = '/usr/sbin/sendmail -bs';


$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'] = 'mbox';

This doesn't send any mail out, but instead will write every outgoing mail to a file adhering to the RFC 4155 mbox format, which is a simple text file where the mails are concatenated. Useful for debugging the mail sending process and on development machines which cannot send mails to the outside. The file to write to is defined by:

$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_mbox_file'] = '<abs/path/to/mbox/file>';

The file where to write the mails into. Path must be absolute.


$GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'] = '<classname>';

Custom class which implements Swift_Transport. The constructor receives all settings from the MAIL section to make it possible to add custom settings.

How to create and send mails

This shows how to generate and send a mail in TYPO3:

// Create the message
$mail = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Mail\\MailMessage');

// Prepare and send the message

   // Give the message a subject
   ->setSubject('Your subject')

   // Set the From address with an associative array
   ->setFrom(array('' => 'John Doe'))

   // Set the To addresses with an associative array
   ->setTo(array('', '' => 'A name'))

   // Give it a body
   ->setBody('Here is the message itself')

   // And optionally an alternative body
   ->addPart('<q>Here is the message itself</q>', 'text/html')

   // Optionally add any attachments

   // And finally do send it

Or if you prefer, don't concatenate the calls:

$mail = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Mail\\MailMessage');
$mail->setSubject('Your subject');
$mail->setFrom(array('' => 'John Doe'));
$mail->setTo(array('', '' => 'A name'));
$mail->setBody('Here is the message itself');
$mail->addPart('<q>Here is the message itself</q>', 'text/html');

How to add attachments

Here is a code sample for attaching a file to mail:

// Create the attachment, the content-type parameter is optional
$attachment = \Swift_Attachment::fromPath('</path/to/image.jpg>', 'image/jpeg');

// Set the filename (optional)

// Attach attachment to message

How to add inline media

Here is how to add some inline media like images in a mail:

// Attach the message with a "cid"
$cid = $mail->embed(\Swift_Image::fromPath('<path/to/image.png>'));

// Create HTML body refering to it
   '<html><head></head><body>' .
   '  Here is an image <img src="' . $cid . '" alt="Image" />' .
   '  Rest of message' .
   ' </body></html>',
   'text/html' //Mark the content-type as HTML

How to set and use a default sender

It is possible to define a default email sender ("From:") in the Install Tool:

$GLOBALS['TYPO3_CONF_VARS']['MAIL']['defaultMailFromAddress'] = '';
$GLOBALS['TYPO3_CONF_VARS']['MAIL']['defaultMailFromName'] = 'John Doe';

This is how you can use these defaults:

$from = \TYPO3\CMS\Core\Utility\MailUtility::getSystemFrom();
$mail = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(
// ...
