About two months ago, I got a LE certificate for my website. Now I got multiple emails telling me a total of four different certs need to be renewed. Unfortunately, I’m also getting these reminders for 3 domains that I’ve never seen before and that I am not responsible for. To me, this looks like there was something wrong with my hosting provider when these certificates were requested over their admin panel (Plesk).
These emails only contain a link to unsubscribe from any further emails. But I have no good feeling, knowing that there are some LE certs for arbitrary domains which for whatever reason seem to be tied to my email adress. How am I supposed to react to these mails stating that these domains would be under my control? Are there any security implications I should be aware of?
