So the two domains I have on my mailinabox instance, the one where the box was configured for the domain is able to send mail freely to att emails. After Client emails through second domain to an att email, suddenly our IP has been blocked by ATT. I’ve contacted ATT and they have lifted the ban but it occurred once again and the next response was that there was something wrong with my SPF records on my second domain but they didn’t discuss it further. I am using Custom DNS with Cloudflare and some of the lights are not green on the dashboard (I’ll post an image here in a minute). Looking for help. anyone?
