Creating emails in MIAB

I have created several emails with their own domains and they are all working except one. Really tripping me out. Everything is perfectly set up correcting with the registar as well as the external dns info. I have checked the external dns info several times to make sure everything is correct. I can send emails with that email address but can’t receive any emails. All the other emails that are all different domains are working fine.

so I guess this isnt working because of the ssl certificate issue. How can I get this resolved?

Have you tried manually running the SSL cert script?
If so, what is the error msg, if any?
