As the name says, a catch-all address is meant to catch all email sent to any non-existing email accounts on your domain.
It can be useful to catch emails that were mistakenly sent to an address that doesn't exist. For example, if the sender made a spelling mistake and typed in "firstname.lastname@example.org" instead of "email@example.com".
Unfortunately, most mails that you catch will be spam. If you decide to use the catch-all feature, we recommend that you create a separate account for this on your own domain, and periodically check if you have caught any emails that you want to keep.
Set up a catch-all address
- Log in to the one.com control panel.
- Click on the Email tile to open Mail Administration.
- Click on the Aliases tab, in the menu bar near the top of the screen.
- Type in the email address that should become your catch-all address and click Verify.
From now on every email that is sent to a non-existing address on your domain will be delivered to your catch-all address.
