          What did you change to make it work? Also, did you setup your mail server information in the global config? Is this a new install of Jenkins or did you upgrade recently?

          I had missed setting the smtp setting in the Editable Email notification in the master confgiuration. That is the reason the emails were not sent.

          For the "Failed to instantiate class hudson.plugins.emailext.ExtendedEmailPublisher" error.

          I deletedthe 4 default triggered that showed up everytime I added a Trigger.

          That did it all.

          What do you mean "the 4 default triggers that showed up everytime I added a Trigger"? Can you capture in a video what you are seeing?
