    Directadmin does not create a virtual host for hence if you try to validate the SSL cert via 443 port it will fail with the error. The certificate for the mail subdomain gets added only in SMTP, POP, IMAP if you have mail_sni=1 enabled in DirectAdmin.

    p.s. The subject has been discussed here many times. Please search the forums for more details.
