Abstract

Embodiments of the present invention provide electronic mail that is easy to automatically setup. Embodiments of the invention provide a mail server appliance that is designed to operate with a support service. Each mail server appliance is pre-configured to use the support service as part of an integrated product. The mail server appliance is configured for ease of installation and maintenance and comprises the hardware bundled with the software applications pre-installed. The mail server appliance is also coupled to the support service and may begin operations almost immediately. The support service serves as the primary relay point for sending/receiving mail for the mail server appliance and provides various supporting features. First, it provides pre-installation services for the mail server appliance. Second, the support service provides flexible operations support. For example, the support service allows the mail server appliance to have a dynamically assigned IP address. In addition, the support service may provide continuous availability and backup services for the mail server appliance.

the configuring comprising;

determining if the mail server appliance has failed to authenticate its request for mail, and

queuing mail for the mail server appliance when the mail server appliance has failed to authenticate.

12. The method of claim 11, further comprising:

receiving a certificate for a second domain that is owned by the mail server appliance; and

configuring the mail servers of the support service to accept and relay mail for the second domain to the mail server appliance.

13. The method of claim 12, wherein receiving the certificate for the second domain that is owned by the mail server appliance comprises authenticating the certificate based on a key assigned to the mail server appliance.
