I’m trying to use my personal email for registering, but I get an error from Discorse: > Email is not allowed from that email provider. Please use another email address. ![Email is not allowed from that email provider. Please use another email address.](https://global.discourse-cdn.com/free1/uploads/univeral_blue/original/2X/8/83f827f127a34a44f3a7479b0fdd274c0f9142de.png) I’m trying to use a personal domain `` **** @conto.dev`` that I have hooked into Fastmail. Does anyone know what might be blocking registration? I’ve never seen this before on other sites, including other Discorse forums. ---

I ran into the same issue while registering my account today. Why would Universal Blue choose to disable the use of email domains which every other organisation I have relations with accepts without a fuzz? I even have DNSSEC, DANE, DKIM, SPF et al in place. I also provide E-Mail-Services to customers, even to government agencies, yet U.B. apparently considers my domains unworthy?
