**Swiftmailer will stop being maintained at the end of November 2021.**

Please, move to Symfony Mailer at your earliest convenience.
Symfony Mailer is the next evolution of Swiftmailer.
It provides the same features with support for modern PHP code and support for third-party providers.
See https://symfony.com/doc/current/mailer.html for more information.
