The following can be done for better deliverability of email, eliminating the vast majority of SPAM or Phishing warnings for your user’s emails.

Your IT department will need to add the following entries in your domain’s DNS records. Let us know once you have added the DKIM, SPF, DMARC and Domain Verification records below.


DKIM
DKIM is a DNS-based email authentication mechanism that helps Mandrill more effectively send mail on your behalf by allowing receivers to verify that we have permission to send your email. 
To enable DKIM, create two CNAME records:

==============================================================================

  • {name: 'mte1._domainkey.your_domain', value: 'dkim1.mandrillapp.com'}
  • {name: 'mte2._domainkey.your_domain', value: 'dkim2.mandrillapp.com'}

NOTE – Replace your_domain with the domain name you are creating the records for in your DNS.
==============================================================================


SPF
SPF is another DNS-based email authentication mechanism. If you don't yet have an SPF record, you'll want to add one for your domain. At a minimum, the value should be the following if you're only sending mail through Mandrill for that domain.
If you already have a TXT record with SPF information, you'll need to add Mandrill's servers to that record by adding `include:spf.mandrillapp.com` in the record (before the last operator, which is usually ?all, ~all, or -all).

==============================================================================

  • v=spf1 include:spf.mandrillapp.com ?all

==============================================================================



DMARC

A DMARC policy is an authentication protocol that can be added to your domain to help protect against fraud and increase deliverability. Mandrill requires a minimum DMARC policy of "v=DMARC1; p=none" to be added to any sending domain. Read more about additional configurations available at dmarc.org.
To Enable DMARC, create and save a TXT record in your DNS with a host:

==============================================================================

  • {name: '_dmarc.your_domain', value: 'v=DMARC1; p=none'}


NOTE – Replace your_domain  with the domain name you are creating the records for in your DNS. 

==============================================================================


DOMAIN VERIFICATION
We need to verify that you have access to an email account or the TXT records for your domain. Create a TXT record in your domain's DNS records with the following value. 

==============================================================================

  • mandrill_verify.your_value

NOTE – Replace your_value with the value provided by RedJade. Contact support@redjade.net to request a domain verification value specific to your domain.
============================================================================== 


Alternatively, we can verify you have access to the domain through an email account by sending an email to an @your_domain address, which will need to be forwarded back to us to complete the domain verification through the link in the email.

Once the domain is verified, we can also set the default sender to be from your domain. This would be the same email address for all outgoing emails.
