I replaced my actual domain with "mydomain.com" for privacy. Nothing else has changed on the server. I was getting these status email every day with no problem before the Yum update. I have no idea where to even begin looking for the reason this is happening, so I'm hoping someone here might be able to point me in the right direction. Thanks.
