Allowed prefixes for Approver eMail
Allowed prefixes for the approver e-mail address are:
- admin@
- administrator@
- hostmaster@
- webmaster@
- postmaster@
Furthermore, the domain part of the approver e-mail address must be identical with the domain which you want to create a certificate for.
I.e. for a certificate order for Mydomain.com the approver e-mail address must be
- admin@Mydomain.com
- administrator@Mydomain.com
- hostmaster@Mydomain.com
- webmaster@Mydomain.com
- postmaster@Mydomain.com
An alternative validation via the email address in WHOIS is not possible
Under the GDPR many registrars - including Domaindiscount24/Key-Systems - will not publish e-mail addresses in Whois per default.
As a consequence a Certificate Authority (CA) is not able to check if a given approver e-mail address is listed in Whois of the respective domain.
The mentioned standard approver e-mail addresses will always work, regardless of Whois. Thus we always advise to use one of these standard e-mail addresses.
If an appropriate e-mail address does not exist, it must be created.
