No. This has nothing to do with DMARC. However your branch might be
relevant.

The issue is that owner notifications from Mailman are sent with
envelope from the sitelist-bounces address in the list's domain. In
cPanel this results in the envelope being from [email protected].

cPanel's Exim configuration apparently only sees this as a valid address
if a list named mailman_list.domain exists which it doesn't. There is
only one 'mailman' list and its name is maybe just 'mailman' or maybe
'mailman_some_canonical_host_name', I'm not sure which but probably the
former, but there isn't a separate 'mailman_list.domain' list for every
list domain.

So then Exim is configured to do sender verification and
[email protected] is not a valid address as far as Exim is
concerned so these owner notifications are bounced by Exim and never sent.

The workaround that Terry and others have implemented is to make an
alias for [email protected] which, cPanel's opinion to the
contrary notwithstanding, I believe is the correct solution as it is the
only way the domain admin is going to see any real bounces.
