I have started to get a lot of those when I send messages to some lists.
I understand what is happening, dmarc identifies my domain as DKIM/SPIF
enabled but when sending a message to a list, both of those will fail.
I don't think there is anything I can do about that in my dmarc
configuration, but I just want to make sure.

Also, if I start checking dmarc on my server (I haven't yet) for
messages coming in to me, is there an intelligent way to determine cases
where they fail because it is a list and NOT send the useless e-mail to
the dmarc address?
