>If you can't delete/remove the cert because you need it until it expires, that's an edge case I haven't previously encountered. I don't know how you might disable those warnings. And really you don't want to disable all warnings, just those for the one cert.

It is a situation, for example, a domain is linked to a contract. So, it has to keep answering until the last day. However, a client might have confirmed the desire to not renew, again, for example. In such case, we wouldn't be able to remove the certificate from the server until the last day.

>As for warnings from your domain registrar, you would need to either de-register the domain or contact them to stop warning you about expiration.

But, some of them are in the interface. So, when you see all your domains, and there's a lot, you might see some of them with About to Expire, or something similar. They would usually indicate that in red bold color, and such. That would get pretty annoying after a while, especially, if you have to connect to such interface on a frequent basis. I may suggest a switch so they would allow us to stop getting those identifiers. That might help.
