DMARC is one of many factors your mail servers need to consider
when deciding whether to accept, bounce or silently drop a piece
of mail.
It is perfectly reasonable to set DMARC as a strong but not
overwhelming factor, and then to write allow lists based on,
for example:
List-Id: <debian-user.lists.debian.org>
which is a pretty good representation that this is Debian mail.
So good, in fact, that RFC2919
https://tools.ietf.org/html/rfc2919
suggests it.
