Filter to block an email with a certain return path

Is there a way to filter out emails that have a certain email in the return path? I assume it can be done as part of the header but it doesn't appear to be working for me. 

Here's what I have that isn't working: 

Header                                            Name: Return-Path

                                                        Contains:   [domain of the email address i want to filter out]

Any help is appreciated. Essentially, I do not know what the valid values are for "Name" in the Header category, and of course Xfinity has no documentation on this.

@NONAMER123 To block individual senders, you need to set up a filter.  On the Inbox page, click on the gear icon in the upper right corner, then on Email Settings.  On the landing page under "Mail", click on "Filter rules".  OR-----open the email from the sender, then click on the "hamburger" icon in the header.  One of the options in that menu is "Create filter rule".

@XfinityRaul​ LOL. Of course I know that already. If i didn't know that, how do you think I would have come up with my filter methodology?

The OP already did that. Their problem is, the filter does not work!

@XfinityRaul  Just to be clear, your comment was totally unhelpful and Comcast's "support" is useless. Get rid of email completely if you're going intentionally gaslight customers and provide useless "advice."

Header                                            Name: Return-Path

You can use any of the Header names in an email with this filter. To filter on the "Return-Path:" header your "Return-Path" "Contains" filter should work. 

I tried setting up a similar filter to yours to flag notification emails from the Forums:

        Conditions:    Header:    Name: Return-Path    Contains: alerts.xfinity.com

This worked. The only thing I can think of that would mess it up is if Comcast/Xfinity delivered these messages to the Spam folder instead of the Inbox. Filters only work on email delivered to the Inbox as it is being delivered. 

Open-Xchange has a page documenting the filters at https://documentation.open-xchange.com/components/middleware/http/7.10.6/index.html#mail-filter, but I'm afraid it isn't doesn't add much to the pitiful information Comcast/Xfinity has posted.
