If you have completed the rest of the process for sending Rezgo notifications from your own domain, please contact us for instructions on updating your DNS. If you’re already comfortable adding DKIM and SPF records, these are the records you will need to create. Note that you’ll also need a verification record that will be provided to you by our support team, so you may want to wait until you receive that to make changes to the DNS.
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:
- One with the name
mte1._domainkey.yourdomain.com* with the valuedkim1.mandrillapp.com - Another with the name
mte2._domainkey.yourdomain.com* and the valuedkim2.mandrillapp.com
DMARC
A DMARC policy is an authentication protocol that can be added to your domain to help protect against fraud and increase deliverability. Beginning in 2024, 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 of _dmarc.yourdomain.com* and a value of v=DMARC1; p=none
*Some domain hosts automatically add ‘yourdomain.com’ after the initial value — contact your domain provider for any specifics
SPF
If you don’t already have a TXT record with SPF information, you’ll need to create one that includes the following:
v=spf1 include:spf.mandrillapp.com ?all
If you do already have a TXT record with SPF information, you’ll need to add Mandrill’s servers to that record by adding the following:
include:spf.mandrillapp.com
This goes before the last operator, which is usually ?all, ~all, or -all.
