Unable to filter messages from certain sender

I subscribe to several newspapers from a very large media company called Gannett. Here are a couple of examples of the “From field”
“Lakeland Ledger” [email protected]
“Tcpalm” [email protected]
As you can see the actual from address is the same. I obviously, need to filter on the name of the publication not the from address.
I haven’t been able to figure that one out.
Thanks.

Pretty sure (just tested) if you filter on received and click on “searched words”, you can edit to “From: Lakeland Ledger” (without the “quotes”) and add that to the words list, that will do it.
Just tried it here, and it found the sender name we asked for, not the email, and filtered on it. You can do a test by asking it to flag the mail, then change to do what you want with it, if it works.
