Mandrill is created by Mailchimp and it is a service used to send transactional emails. In order to help with your mail deliverability Madrill requires that every domain that you use for sending emails is configured correctly.


In order to allow Mandrill to send authenticated emails on your domain’s behalf you will have to include them as part of your SPF record. 

The SPF mechanism used by Mandrill is:

Mandrill use their own domain as part of the Return-Path address (used by SPF) and hence SPF alignment would not occur. However, this can be modified as per the article below.
