Where I see freemail addresses in the reply-to in valid mail is in various mailing list platforms, ones that work around DMARC blocking by rewriting the from, then moving the original poster's email address to the reply-to, to allow for off-list replies. Not so much that I'm looking to argue whether or not this is valid or really common or should be allowed, just saying that I see it today. :)
