if you want to receive mail from gmail, you have to manually copy and paste the ssl private and public key you created for your domain to the email domain. however, letsencrypt certificates are renewed every 3 months. when the domain is automatically renewed, does letsencrypt renew the same certificate or create a different certificate? this is important because if the certificate changes, you have to copy and paste the private and public keys to the email domain again, otherwise you can't get email from gmail etc. if this is the case, it would make sense to automate this process in future versions of aapanel.
