Registering Domains Parent topic

When registering domains to the Trend Micro Email Encryption Server, messages are sent to the following email addresses to verify ownership of the domains:
  • postmaster@<domain>
  • webmaster@<domain>
  • the email address returned from a WHOIS lookup for the domain
WARNING
WARNING
The postmaster and webmaster accounts must exist and be enabled before domains can be registered.
Trend Micro sends a message to the "Contact Information" email address to verify that the domain exists and that the postmaster@<domain> and webmaster@<domain> accounts exist and are enabled.
WARNING
WARNING
One of the following must respond to the verification message:
  • postmaster@<domain>
  • webmaster@<domain>
  • the email address returned from a WHOIS lookup for the domain
By design, after a domain is registered, it cannot be re-registered. If a domain has already been registered, subsequent re-registration results in a "domain already registered" error. This is enforced for the purpose of security. If there is a need to reinstall IMSVA, backup the database prior to re-installation, and restore it afterwards. This eliminates the need to re-register IMSVA and the same domains after re-installation.
Note
Note
IMSVA must be registered to the encryption service before any domains can be registered.
The default sender address for your domains will be postmaster@<domain>. You can customize the default sender address from the Encryption Settings screen.
The default sender address is used when IMSVA tries to encrypt a message, but whose domain is not in the Domain List. IMSVA signs these messages with the default sender address.

    Note
    Domains and their sub-domains are treated as unique entries. Sub-domains must be added separately to the domain list.

    LDAP groups (entries starting with" LDAP") cannot be added to the domain list.
  5. Click Save.
    A progress bar appears as the domain information is sent to the Trend Micro Email Encryption Server. A confirmation screen appears that verifies the domain information was received by the Trend Micro Encryption Server.

    The domains appear in the Domain list on the Domain tab and a message about the Domain tab.
  8. If you are the registered owner of the domain, reply to the confirmation message from the Trend Micro Encryption Server. The message is sent to postmaster@<domain> and webmaster@<domain>. When your domains are approved, you receive the domain ownership verification key file. You must reply to the confirmation message to prove that you are the owner of the domain.
    Note
    Note
