Notes on Capabilities
DMARC: Mandrill will use default authentication (for DKIM and SPF) unless customer configures account to use the customer's domain for authentication: http://help.mandrill.com/entries/21751322-What-are-SPF-and-DKIM-and-do-I-need-to-set-them-up-
DKIM: Can be configured to use customer's domain. See link in SPF notes.
SPF: Can be configured to use customer's domain. Log into dashboard then goto Settings -> Domains -> Tracking and Return Path Domains. This section will allow you to use your DMARC domain in Mandrill-based messages.
When deploying DMARC, domain owners often find new sources of email.
Domain owners then wonder if the source is capable of sending DMARC compliant email.
This directory contains information on the capabilities of various sources of email.
