Filter Question: How to filter emails from forwarded account

Hello,
I have an old business account from a different domain. It is now set as a forward to my new domain email account.

I want to filter the items that I receive as a forward from the old account and automatically place in a folder. Each of those emails contains the "from" email address plus " via <olddomain.com>". I tried to filter by that "via" text, but it does not work.

Any ideas how to filter those emails?

Thank you,
Byron
