Virtual Domains

If the mail server is to receive mail for a domain, a virtual domain must be configured for each domain for which it is to receive mail. This sections allows configuration of the virtual domains to be handled by the server.

The main screen will display a list of all the virtual domains currently configured on the mail server. To add a new virtual domain click New Virtual Domain.

A new window will appear, Create Virtual Domain.

Virtual Domain

This is the domain for which the server will be receiving mail.

In the example being used in this document we want to receive mail for corp.guardiandigital.com. So we would set the virtual domain to that.

Postmaster

The postmaster is an e-mail address of a real user that will act as a default (sometimes called a ``catchall'') e-mail address. In the event that an e-mail is sent to a user that doesn't exist in the virtual domain, the postmaster of that domain will receive the mail. This is an optional field. If the postmaster is not defined, mail to unknown users will be rejected.

• [NOTE:]In the example being used in this section the relay mail server, smtp.corp.guar-diandigital.com would not have this virtual domain set on it. It is relaying mail for that domain, not receiving it. (It would have a mail route for this virtual domain instead which would redirect the mail to its final destination).

  This virtual domain would be configured on the mail.corp.guardiandigital.com server instead.

Once all the required fields have been completed click Create Domain for this domain to be created.

Once the virtual domain is added, it will be displayed on the list of virtual domains on the main screen. To edit a virtual domain click on the domain. A new window will appear similar to the Create Virtual Domain menu. Here the options to delete or update the virtual domain can be found.

To add new addresses to this virtual domain, click New Address. Now you can enter an Address and a Recipient. Click Create Address to create this address. The mail server will receive mail for the Address, and forward it to the Recipient. The recipient can be a local user-name or a full email address. All created virtual domain addresses will be displayed on the Edit Virtual Domain window. In this example, the mail server will receive mail for support@corp.guardiandigital.com and deliver them to the local user ryan.
