build.rokers.io: Create email for build notifications

[gmacario]

I plan to configure https://build.rokers.io/ to notify build failures via email.

The notifications are usually sent from a dedicated email address.

@ludusrusso : Would you be able to provide me the following information

• email (i.e. something like build-admin@rokers.io)
• Details of the SMTP server to be used for sending emails from Jenkins:
  • IP Address/port
  • Use SSL?
  • Username/password for server authentication
