Feature: #88643 - New Mail API based on symfony/mailer and symfony/mime ¶
See Issue #88643
TYPO3 has relied on the third-party dependency “SwiftMailer” for a long time.
However, the library has been superseded by the author in favor of new, more modern libraries “symfony/mailer” for sending emails and “symfony/mime” for creating email messages.
TYPO3 has replaced swiftmailer with the symfony components.
The new component does not handle the regular PHP function
has been declared unsafe in various scenarios anymore. Instead, it is recommended
to switch to
, which can be configured within the TYPO3
Install Tool or the Settings module for System Maintainers under “Presets” => “Mail”.
All existing installations which still have “mail” are migrated to “sendmail” by automatically detecting the sendmail path by checking PHP.ini settings, but should be reviewed on update.
In addition, the MailMessage API to create Email messages now inherits from
, and adds certain shortcuts
and more flexibility, but is also stricter in validation.
Especially custom extensions using the MailMessage API need to be evaluated, as it is not possible anymore to add multiple email addresses as a simple associative array but rather a NamedAddress object or a simple Address object from “symfony/mime”.
All existing Swiftmailer-based transports which TYPO3 supports natively have been replaced by Symfony-based transport APIs.
Spool-based transports are still experimental, as it might be replaced by a native Symfony component as well.
The MailMessage API now has more possibilities to add multi-part files and attachments, for use in third-party extensions, but some APIs might be adapted.
See the documentation of the Symfony components ( https://symfony.com/doc/current/mailer.html ) for further details on how to use the new Email class where TYPO3’s MailMessage class extends from.
An example implementation within a third-party extension:
$email = GeneralUtility::makeInstance(MailMessage::class) ->to(new Address('email@example.com'), new NamedAddress('firstname.lastname@example.org', 'Benni Mack')) ->subject('This is an example email') ->text('This is the plain-text variant') ->html('<h4>Hello Benni.</h4><p>Enjoy a HTML-readable email. <marquee>We love TYPO3</marquee>.</p>'); $email->send();
It is however also possible to re-use a Mailer instance, also adding custom Mailer settings via a custom Transport for special cases.
$mailer = GeneralUtility::makeInstance(Mailer::class) $email = GeneralUtility::makeInstance(MailMessage::class) ->to(new Address('email@example.com'), new NamedAddress('firstname.lastname@example.org', 'Benni Mack')) ->subject('This is an example email') ->text('This is the plain-text variant') ->html('<h4>Hello Benni.</h4><p>Enjoy a HTML-readable email. <marquee>We love TYPO3</marquee>.</p>'); // Send the email via the Mailer instance $mailer->send($email);
