    Hey,

    little question:

    can i use the lets encrypt certificate what i created for my domain.tld for ftp tls and mail tls instead of the self signed? The "certificate is not Trustworthy" warning annoys me.

    Best regards

    Okay - the cert is created for domain.tld but my host system is on hostname srv01.domain.tld - will it also work?

    it will provide hostname mismatch error.

    Can this be prevented?

    by providing a cert with the actual hostname in it.

    ssl certs are based on domain names, not ips.

    An ssl mismatch of a letsencrypt cert is not different from an ssl mismatch of any other ssl cert.
