Lisa: email abouted failed certificate renewal


today I received an email from the lisa server that the certificate renewal failed for my domain.
I know lisa got migrated. Is this email an artefact and can be ignored or do I have to take any action?

Thanks, Daniel


If at any point you had used custom mail and webmail domains and then changed the DNS away, you should get the failure notices as LetsEncrypt certificates need to be renewed every 3 months.

Until recently I suppressed these messages.
