I’m using mailcow for a few weeks, hosting few domains. I have configure SSL for each domain, but today my e-mail client notify me that SSL is not valid for the domain.
The SSL has been replaced with the SSL of the server name.
The ACME log say:
xxxx.live.xxxx - Found orphaned certificate: mail.xxxx.mk - archiving it at /var/lib/acme/backups/mail.xxxx.mk/
