What is default mail routing?

This article explains how default mail routing operates on the Donhost hosting platform.

This article applies to Shared Hosting, Reseller accounts and Dedicated Servers.

Any mail sent to an address at your domain which is not specifically defined as a Mailbox, Forward or MRA will be routed according to the rule you define on the Default Routing page. This is sometimes referred to as a catch-all email address.

Login to your Donhost control panel.


Browse to the Default Routing page for the desired account.

The resulting page will display the currently configured settings for default mail routing as well as the modification options available, which are defined below;

Send To POP3 Mailbox

With this option selected, default mail will be sent to the mailbox on our server which you choose from the drop down list. You must first create a mailbox before you can route your default mail to it.

Send To Address

With this option selected, default mail will be sent to the address you enter in the text box. This option should only be used for external addresses, for internal addresses (i.e. other addresses at your domain name) it is more efficient to use the Send to POP3 Mailbox option.

Bounce Mail

With this option selected, default mail will be returned to the sender with a message attached explaining that the address does not exist.

Please note: Bouncing your default mail can cause problems for mail servers attempting to deliver a large number of bounce messages to the non-existent sender addresses as used in most junk email messages and your domain may be abused by spammers to relay junk email messages.

Delete Mail

With this option selected, default mail will be deleted at server level without failure notification message being issued to either the domain holder or the sender of the email.

Select the radio button for the option appropriate to your requirements and click Modify Default Routing. The server configuration will be updated immediately
