just for info - reverted back to 2.15 and all is working.

I guess this has been cause by https://github.com/jenkinsci/email-ext-plugin/commit/e03015739c3161d173dbe48c2842f3d5b3590743

No, I don't think that's the cause. That commit is just reverting an earlier feature addition. I'll double check this, but the testing I did did not have this issue. To be honest, 2.16 probably should not have been released without more testing from the community. It was done as part of an overall Jenkins release.

I misunderstood when I first looked at this issue. The global default recipients is no longer supported. Please use an environment variable and the ${ENV} token to do what it did. The global default recipients list caused issues in other places. The global default recipients field should be removed from global config and will be as soon as possible.

Why is Recipients any different from Subject or Content. This is an extremely important feature to have in a large Jenkins installation with a lot of projects. Having to set the recipients in each project is both tedious and error prone.

How can using an ENV variable cause less issues than a separate configuration parameter?

If you are serious about removing this feature, then five things need to happen ASAP:
1. Remove the "Global Recipient List" documentation from the Wiki page
2. Document in a very prominent way in the changelog on the Wiki page that this feature has been removed
3. Document on the Wiki page how to convert from using "Default Recipients" to using an ENV
4. Remove the "Default Recipients" input field in the Manage Jenkins user interface
5. Release a new version of the plugin, which include these fixes

Is there anything we can do to make you change your mind about this, to help creating patches or to help with testing?

I'm totally with Dennis! o/

Sure, feel free to submit patches. I think the main issue is with PROJECT_DEFAULT_RECIPIENTS in the triggers. Perhaps not adding it by default would be a good solution. For patches you'd want to start with the 2.15 branch.

There is still a fairly large interest in this feature. Will revisit.

I've submitted a very similar issue regarding DEFAULT_RECIPIENTS in the email-ext plugin:
https://issues.jenkins-ci.org/browse/JENKINS-11940

Yes, this issue indeed has large interest.

Please try forking this repo and building, it should revert all removal of the DEFAULT_RECIPIENTS from head. https://github.com/slide/email-ext-plugin

You can issue pull requests if you see anything amiss.

Will this remain as a fork of email-ext or will the re-implementation of DEFAULT_RECIPIENTS be added to the next release of the plugin?

The goal of this is to get it tested/fixed prior to merging with mailine and getting a release.

That is the goal, I have a version I am testing currently.

Appreciate the update. Just took over someone else's installation and am new to jenkins administration. Reverted back to 2.15 for now since that seems to work (they were only on 2.16 anyway).

How can I find the 2.15 build? All I see is the source on github.

Does anyone have a config.xml for a job that was from before the default recipients was added (pre 2.14). I would like to add some tests for upgrading to make sure nothing gets broken.

Fix JENKINS-11683, JENKINS-1144, JENKINS-11665

Compare: https://github.com/jenkinsci/email-ext-plugin/compare/3789acf...09296a6

Fixed in 09296a6

I'm a bit confused. Did this get released? If so, in what fix version? I'm not seeing any references to this in any of the change logs.

Yes, it did get fixed in 2.19. I missed putting it into the changelog.
