I am not very tech savvy, but today I had two emails in my spam folder that look like they were from Sunshine Rewards yet they were "undeliverable" due to being "Unauthenticated email address." The email had no content; just lines of error descriptions, etc. I normally get email from SR in my inbox with no problems, so I am wondering if my settings have gone haywire. Plus, I am curious what I missed! Anyone have any insight? Thanks!
