Problem with catchall email

Hi,

I setup the catchall email in our virtualmin, i followed this one https://www.virtualmin.com/documentation/tutorial/admin/how-to-create-a-...

It works fine i can receive emails even from invalid email alias.

The problem is that it also forwards my existing user email. How can i exclude my existing email?

Example catchall@domain.com = the catch all email.

blahblah@domain.com = a non existing email. It works fine emails from this address is forwarded/sent to catchall@domain.com

bounce@domain.com = existing email account. But problem it wont receive. Emails are forwarded/sent to catchall@domain.com when i set "Additional email addresses: @domain.com". This should be on its own inbox.

fbl@domain.com = existing email account. But problem it wont receive. Emails are forwarded/sent to catchall@domain.com when i set "Additional email addresses: @domain.com". This should be on its own inbox.

Thanks in advance
