I've configuring jobs with the Job DSL plugin.
I have a Seed job whose workspace contains the job descriptors as Groovy DSLs

They make use of Email Ext
The jobs are reporting in the console log that they are sending emails as a post build process.
No emails are arriving.

If I go to the configure page in the GUI and do nothing but click save, next time the job runs the email does get sent.

I've attached the job configs xml. There are differences but I haven't been able to work out which diffs means the post build trigger successfully delivers email
