Notes on Capabilities

DMARC: MailChimp will use default authentication (for DKIM and SPF) unless customer configures account to use the customer's domain for DKIM authentication. MailChimp info: http://kb.mailchimp.com/delivery/deliverability-research/set-up-mailchimp-authentication

DKIM: Can be configured to use customer's domain: http://kb.mailchimp.com/delivery/deliverability-research/set-up-custom-dkim

SPF: SPF is not possible as MailChimp uses their own domain in the bounce address. Their domain authentication verification tool requires including Mailchimp, though. To work-around this without having to include Mailchimp servers, try including only 'ip4:205.201.128.0/20 ip4:198.2.128.0/18' in your SPF record.

Sources

Domain owners then wonder if the source is capable of sending DMARC compliant email.
