How do you notice that? DMARC has only an effect if the sender domain
has a reject policy and SPF fails. Thats very rare!!!

Try the following: create a dmarc dns record with p=reject for your
domain (spamresource.com), then post to this list. The list makes spf
fail and when dkim is also failing you will get a reject.

Currently your domain has p=none, that will never make you trouble.
