Thanks dmorris, jcoffin, and cblaise ! Got it figured out. It was indeed on Hostgators end not delivering the email. So strange that hostgator relayed the emails for months and then just decided to stop but that is what happened. Changed settings to use gmail as a relay and they are working perfect again Hostgator is a crap host, will be looking into a better host in the coming months when my package expires.

Thanks again dmorris for the direction/insight. Read through all the cron jobs and dug through all the scripts in usr/share and learned a lot about how untangle works (and it answered a lot of questions I had.) Cool stuff. Follow your git and jira... Nice how you can tag along through the dev process. Its also nice how everything is documented like here . Well done guys!
