i have Hestia cp with exim4 as a mail server, they are on ubuntu on AWS. the main domain has an SSL from sectigo and the [login to view URL] use Let's Encrypt SSL. everything was running smoothly for several months, however yesterday a wired problem happened. the mail clients unable to verify the certificate of the mail because it's saying it's from Sectigo (which is wrong it should be let's encrypt).
when i go to the web mail ([login to view URL]) the ssl works fine but the mail clients are seeing the wrong certificate.
on hestia i tried to regenerate the SSL but i got the following error "Error: DNS record for mydomain doesn't exist" eventhough it does exist
