EmailSenderListener adds significant overhead

[schmittjoh]

Right now, the EmailSenderListener seems to be executed on each request regardless of whether an email is being sent or not. In my case, this makes each request about 1 second slower.

you mean EmailSenderListener ? i guess this listener should really be lazy registered only when an email is actually send. for this we would likely need to wrap the standard swift mailer, which might also help in making the entire service a bit more lazy loading in general to make it more feasible to inject the mailer into services without it causing a lot of overhead.

[schmittjoh]

yes, EmailSenderListener. I don't think it's the initialization of the mailer service itself (though that should be avoided at best as well), but rather that a network connection with the server is being established even if there is no email to be sent.

Please open it in the appropriate issue tracker. SwiftmailerBundle is in its own repo now, and this does not affect 2.0
