What is a catchall address?

A catchall address is a designated mailbox where any email sent to a non-existent email address will be delivered. To better help explain catchalls, review the example below:

You have the following mailboxes setup on your account:

bill@yourdomain.com (Which is set as the catch-all)

Now in this example, any email sent to john@yourdomain.com would be delivered to that corresponding mailbox.

The same would hold true for any email sent to bill@yourdomain.com.

However, what would happen if an email was sent to “frank@yourdomain.com”?

Because the mailbox frank@yourdomain.com has not been setup in the system, normally the email would be rejected with a “user unknown” message and would be returned to the sender.

However, if you have a catchall setup, like in the example above, the email would be delivered to the catch-all mailbox which in this case is ‘bill@yourdomain.com’

This would hold true for email sent to any other addresses which have not been setup as mailboxes on the system (ie anythinghere@yourdomain.com)

We sometimes also refer to this email address as the Default Email.
