How can I set the Sender's address in Jenkins?

Jenkins uses the System Admin e-mail address as the sender address for e-mail notification. You can configure this under Manage Jenkins -> Configure System. This is under the Jenkins Location header on that page! It is not immediately obvious that this setting is tied to the e-mail notification settings, since it is not under the E-mail notification header on the configuration page.

Manage Jenkins -> Configure System -> Jenkins Location -> System Admin e-mail address

You can search the page for "Jenkins Location" to change the default value of address not configured yet to whatever you want.

There are two places to add the "E-Mail Notificaitons"

1. Global level
2. Local level (Jenkins job level)

To set the E-Mail Notification at Global Level, follow below steps -1) Go to Manage Jenkins2) Configure System 3) Jenkins Location 4) System Admin e-mail address

To set the E-Mail Notification at local level (per Jenkins job level), follow below steps -1) Click on the Job name (if existing one)2) click on the "Configure"3) Then look for the "Post-build Action"4) Specify the email address under "E-mail Notification".5) Save the changes.
