AOL and Yahoo have published policies that they do not allow anyone to use email addresses at their domains from anywhere but their mailservers. If you're sending mail with aol.com or yahoo.com email addresses in the From: field you'll see errors just like the ones you're seeing. The misuse of DMARC by those two ISPs means that you cannot run a functional discussion mailing list if you have any subscribers at any of those domains. Your two options are to tell your subscribers to move to an email provider that allows their users to use mailing lists, or to configure your mailing list software to use fake email addresses in the From: field (ideally just for users from Yahoo and AOL). Depending on what software you're running it may well have a feature to do that in place that you just need to turn on. The issue isn't related to your DMARC records (if any; you likely shouldn't be publishing any), nor your SPF or DKIM records, and there's no change you can make to those that will fix things. It's that AOL and Yahoo broke email for their users, and you need to work around that.
