Any e-mail that is sent to an unknown account at your domain name, such as firstname.lastname@example.org, gets automatically rerouted to your default e-mail account. All web site accounts are automatically assigned a default e-mail address - email@example.com - which you can change, if required.
To set your default e-mail address:
Click on the Default Address link in the Mail area.
Click on the Set Default Address link.
Enter the complete e-mail address of the new default in the field next to your web site name drop-down list.
Note: You can enter :blackhole: to throw away all incoming mail, or :fail: no such address here to bounce the e-mail back to the sender. Of the two :fail: is the better choice, as it will reject mail before accepting the entire message, keeping the mail server running a little smoother.
Click on the Change button. Your new default e-mail address has now been set.
