As @javiereguiluz stated in symfony/symfony#11494, the way to report bugs can be improved. One of the things that could be done, is to add a note to make a bug reproducable by forking the Symfony Standard Edition with the modifications needed to reproduce a particular issue.

since https://github.com/symfony/SwiftmailerBundle/pull/64 flushing the memory spool manually is not necessary anymore when using Symfony 2.3+. I added a versionadded note here, but we might decide to remove the obsolete paragraph instead, making the cookbook only about generating urls (which would require renaming the page then)
