Running the Email Extension plugin - version 2.14.1 with Jenkins 1.424.6 - I had the Jenkins URL set incorrectly which was causing broken images and the wrong rooturl in my email-ext status message after a job built (using the HTML and the included templates). Fixing the Jenkins URL did not fix it. I then upgraded to Email-ext version 2.19 with Jenkins 1.457. This also did not fix it. I'm confused because if I "echo %rooturl%" as a Windows Batch script as a build step - it gives the right response. I can't see any place that the plugin could be caching this info.
