Enable Wildcard This option is only available with a DynDNS account.
Enable the wildcard feature to alias subdomains to be aliased to the same IP address
as your (dynamic) domain name. This feature is useful if you want to be able to use,
for example, www.yourhost.dyndns.org and still reach your hostname.
Mail Exchanger This option is only available with a DynDNS account.
DynDNS can route e-mail for your domain name to a mail server (called a mail
exchanger). For example, DynDNS routes e-mail for john-doe@yourhost.dyndns.org to
the host record specified as the mail exchanger.
If you are using this service, type the host record of your mail server here. Otherwise
leave the field blank.
See www.dyndns.org for more information about mail exchangers.
Backup Mail
Exchanger
This option is only available with a DynDNS account.
Select this check box if you are using DynDNS’s backup service for e-mail. With this
service, DynDNS holds onto your e-mail if your mail server is not available. Once your
mail server is available again, the DynDNS server delivers the mail to you. See
www.dyndns.org for more information about this service.
