if you want to receive e-mails from CI builds that include your
commits you need to go to builds.apache.org and edit your e-mail
The easiest way to do that is to type your name in the search box at
the right top and then click on configure, if you're logged in there
should be a e-mail address field, make that the same as the e-mail
address you configured in git.
I think this change is because of the use of email-ext plugin we now
use on Jenkins to send notifications, and it checks if it's a known
user so no spam is sent from Jenkins.
