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.
