I am trying to use the play plugin for sending emails:
https://github.com/playframework/play-mailer
I have followed the instructions as found on github: adde
The README is up to date with the latest development (upcoming version). As of 19/12/2014, the latest version released and available in the Typesafe repository is 2.3.1. If you want to use this version you need to refer to the README in the v2.3.1 tag: https://github.com/playframework/play-mailer/tree/v2.3.1
For the upcoming version we have decided to break compatibility to move the Play mailer into its own package and provide a better implementation. That's the reason why the documentation in the master branch is not working with version 2.3.1.
