Jenkins email plugin doesn't send email to user who broke the build

Question

I\'ve setup Jenkins to send emails only to users who broke the build using email-ext plugin, but I\'m getting this error:

Not sending mail to unregist

Answer 1

Put the line bellow in your jenkins startup script

-Dhudson.tasks.MailSender.SEND_TO_UNKNOWN_USERS=true

The newest Jenkins security directive only allow sending mail to registered user. The line above bypass this configuration.
