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

OK, after some experiments this is what I found out:

Jenkins takes the email part of the committer (not the author). For example for a commit message that looks like that:

Author: John Smith   2017-07-27 17:15:39
Committer: John Doe   2017-07-27 17:15:39
Parent: 9c3ff18dda8ca6f7b7ac4ebab4c76d3c85891a33 (commit)
Branch: master

Jenkins will take "committer1", and create a brand new user under People with User ID "committer1" and email "". Unless that user has a password however, it will be considered unregistered so you need to go to Configure for that user and add a password field to it:

So this is one way to fix the error, but you have to do it for every user and in a big team it can be tedious.
