Answer
Make sure SMTP server is configured under "Manage Jenkins" -> "Configure System" -> "Extended E-mail Notification"
Note also that depending on your plug-in set up, you may have another place to configure SMTP server. For example under "Manage Jenkins" -> "Configure System" -> "E-mail Notification".
That is not needed for this particular plug-in but it may lead you think you have everything done, while it is not :)
