I'm not posting the whole thing because I'm scared I'll inadvertently leave something identifying. And the header seems massive.
But I'll post the message ID bit that mentions mailchimp. I don't know if that will help, sorry. If you could tell me if this could be weaved into a sieve rule I'd be grateful

Would this work, feel free to laugh if it is badly wrong
if header :contains "X-Mailer" ["MailChimp"]
{reject }
