The Brixly Workspace is purchased on a per-domain basis, with the ability to host mail under a single domain. However, you are able to add additional 'alias' addresses to the account.
Once you have added an Alias Domain, you may wish to forward all emails that come in through the alias domain, to the equivalent mailbox of your primary domain.
For example, if we had 'brixly.uk' as the 'primary domain', we may wish to forward all requests from the .com equivalent to the primary, brixly.uk.

To add a new Email Forwarder, scroll down and click 'Email Forwarders'...
Next, click the 'Email Domain Forwarder' tab located here, and click 'Create Domain Forwarder'...
