The package can also facilitate a smoother migration from the old Swiftmailer package to the new Symfony/Mailer package. Getting Started --------------- [](#getting-started) ``` $ composer require neos/symfonymailer ``` Configuration ------------- [](#configuration) The package provides a default configuration for the Symfony/Mailer package. You can override the default configuration by adding the following configuration to your `Settings.yaml`: ``` Neos: SymfonyMailer: mailer: dsn: 'smtp://localhost' ``` The `dsn` parameter is the only required parameter. It should be a valid DSN string for the Symfony/Mailer package. If you migrate from Swiftmailer, you can use the following command to generate the DSN: ``` ./flow symfonymailer:migrate:generatedsnfromswiftmailer ``` Usage ----- [](#usage) You can test the mailer configuration by sending a test email: ``` ./flow symfonymailer:test:send --from="team@neos.io" --to="jon@doe.com" --subject="Test email" --body="This is a test email" ``` The package’s design principle is to minimize modifications to the original mailer package. Consequently, only the classes of Symfony/Mailer are utilized for emails, attachments, and so on. The package solely provides a service to initialize the mailer with the configuration. Additionally, the package provides a command to send test emails and migrate the SwiftMailer configuration to an appropriate DSN for Symfony/Mailer. If you use the `LoggingTransport` or `MboxTransport` from SwiftMailer, there is no replacement for the Symfony/Mailer package. **Basic Example** ``` #[Flow\Inject] protected MailerService $mailerService; public function sendEmail(string $from, string $to, string $subject, string $body): void { $email = new Email(); $email ->from($from) ->to($to) ->subject($subject) ->text($body); $mailer = $this->mailerService->getMailer(); $mailer->send($email); } ``` Migrate from Swiftmailer ------------------------ [](#migrate-from-swiftmailer) As previously mentioned, the package includes a command to generate a DSN from the Swiftmailer configuration. To utilize this command, you must have the Swiftmailer configuration located in your `Settings.yaml` file. You can use the following command to generate the DSN. ``` ./flow symfonymailer:migrate:generatedsnfromswiftmailer ``` The PHP code within your package requires some modifications. To facilitate the migration process, there are several rector rules available that facilitate the transition from Swiftmailer to Symfony/Mailer. - [SwiftMessageToEmailRector](https://getrector.com/rule-detail/swift-message-to-email-rector) - [SwiftCreateMessageToNewEmailRector](https://getrector.com/rule-detail/swift-create-message-to-new-email-rector) - [SwiftSetBodyToHtmlPlainMethodCallRector](https://getrector.com/rule-detail/swift-set-body-to-html-plain-method-call-rector) Utilizing these tools, it is feasible to migrate your codebase to Symfony/Mailer. ### Health Score 48 — FairBetter than 93% of packages Maintenance68 Regular maintenance activity Popularity36 Limited adoption so far Community24 Small or concentrated contributor base Maturity54 Maturing project, gaining track record Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
