Broken link

[SofHad]

The EmailSenderListener link is broken, because the api class does not exist.
on this page: http://symfony.com/doc/current/reference/dic_tags.html#kernel-terminate

Hmm, indeed. Swiftmailer is no longer part of core Symfony, so it's no longer rendered there. I'm +1 for removing the API link, but maybe we can link to the api docs of swiftmailer? /cc @fabpot

I don't think the API docs of swiftmailer are rendered online, but you could link to the source on github
