Content Filtering - syntax for deleting all messages from a domain displayed in the header text

I am trying to create a Content Filtering rule, using wildcards, that will delete ALL incoming emails that mention a particular domain in the header text.

E.g.: Delete all incoming email with the text [*.click] in the Return-Path header.

What I've done (that isn't working):

Create a rule called "Blacklist"

Match type "ANY condition must be met"

Enable wildcards ON

Action: Delete Message

Condition: contains specific words or phrases

Field: Email header

Comparison: Contains

*.click

So for this header example,

"Return-Path: <sara_martinkus-myname=mydomain.com@loudmixes.click>"

do I need wildcards on both sides of the phrase, like this? [*.click*]

Thanks for your help!
