You are seing it yourself. Their e-mails fail SPF allignment, SPF authentication and DKIM authentication. As a consequence, they fail DMARC.
I see a deluge of DMARC failures, mostly from forwarding accounts, mailing lists, and the mass mailer musvc.com I do not have the resources to contact them for cyber spaking/slap/disciplining. Their e-mails are going where they belong. If they do not care about the quality of what they send out, why should I care about their negligence?
