W开发者_如何学编程hat part of Symfony2 needs Swiftmailer?

It's not used by the demo-controllers.

I am wondering b/c I am trying to figure out how to put Symfony2 on a diet without inhibiting the administration / debug interface.

This is not for Marketing. Symfony2 uses Swiftmailer as a mail sending library. If you don't plan to send any mails within your application, you might try to remove SwiftMailer from the vendors.
