The admin email comes from the Jenkins Location area of the Global Configuration if it exists. Are you saying you can't change it in that field in the Global Configuration?

Changing the email address in that location through the web UI doesn't work, that's the core issue here. It will look like it worked, as the display will save and update if you go out and back into the Global Configuration, but it won't change when the system sends out emails.

It used to work until one of the recent plug-in updates, as in our workflow we change this from address about every three weeks or so. To get around this for now, I've had to manually edit the file jenkins.model.JenkinsLocationConfiguration.xml on the Controller, as Gunnar has noted in this ticket's Description.

Ok, I'll take a look.

fyi basil

I wrote a simple test and determined through bisection that this was working as of email-ext 2.71. The regression occurred in email-ext 2.72 as part of commit 1160d45.

The specific lines of commit 1160d45 that introduced the regression are the following lines:

@@ -226,15 +236,20 @@ public final class ExtendedEmailPublisherDescriptor extends BuildStepDescriptor<
     }
 
     public String getAdminAddress() {
-        JenkinsLocationConfiguration configuration = JenkinsLocationConfiguration.get();
-        assert configuration != null;
-        return configuration.getAdminAddress();
+        JenkinsLocationConfiguration config = JenkinsLocationConfiguration.get();
+        if(config != null) {
+            if(StringUtils.isBlank(mailAccount.getAddress())) {
+                mailAccount.setAddress(config.getAdminAddress());
+            }
+        }
+        return mailAccount.getAddress();
     }

Reverting this hunk at commit 1160d45 fixes the problem, though I am not sure if it breaks anything CasC-related.

The default account appears to have been intended to use the email address from Jenkins Location, as an Admin Account Address field is not displayed for it in the Jenkins UI. However, additional accounts appear to have been intended to store their own addresses, as the UI shows an Admin Account Address field for each one.

There appear to be a few bugs in this logic. As noted above, the email address for the default account seems to be copied from the Jenkins Location but never updated when the Jenkins Location email address changes. Another theoretical problem is that hudson.plugins.emailext.ExtendedEmailPublisher#createMail uses the address from the default account even when the session (created in hudson.plugins.emailext.ExtendedEmailPublisherDescriptor#createSession) picked an additional account. I say "theoretical problem" because this functionality has no integration test coverage, nor is there an integration test for the migration logic.

Fixed in jenkinsci/email-ext-plugin#249.
