Basic setup question for a domain

I’ve just setup. Here’s what I did. I use Essential Pim as my email client.

  1. Setup runbox account
  2. registered my domain with runbox
  3. Changed mxrecords, spf, cname appropriately so my emails would go to runbox.
  4. Registered 2 aliases in runbox, one myname@mydomain.com and one nospame@mydomain.com

Now this is what is happened. . - All my emails went to myname@runbox.com - I used the catch-all, so everything to *@mydomain.com went to myname@runbox.com

I can use filters to force my two email addresses which are now aliases into folders under my runbox account address, but is there any way to send my emails to the same accounts I’ve been using? I had an account myname@mydomain.com and I’d like my emails to that address going to the same account folder it has always gone to.
