How can you get a lower reputation? Afaik dmarc is just signing your outgoing
messages.
DKIM is signing of headers. DMARC is policy (like "This domain must sign all messages with
DKIM, no exceptions, and has strict SFP") and reporting mechanism for other hosts ("We
get mail from you and this message violates declared policy of your domain").
As I get these reports, it means that messages from "my domain" (really,
forwarded by mailing list software) violate policies set by my domain. It means, my
domain is compromised somehow.
