How to Set Up Your DNS for Outgoing Email

If your domain is hosted externally and you want to send email from your Hypernode, there are some DNS records that need to be added to the external DNS.

In order to stop spam, and ensure reliable delivery of your webshop’s emails, you must first authenticate your domain, and set up SPF, DKIM, and DMARC, DNS records.

Adding DNS Records

Please add the following DNS records to your nameservers, to authenticate your domain. If you already have an SPF record (the fourth record in the table) in place please check out our documentation on SPF, or contact our support for assistance on how to merge the SPF content into your existing values.

Name	Type	TTL	Content
x-transip-mail-auth.example.com	TXT	600	f491ddb3e61d1c92ab6de9f81257b1c0b95986d6550517f005c8e5e895da6fd2
_domainkey.example.com	TXT	600	o=~
hypernode._domainkey.example.com	CNAME	600	hypernode._domainkey.example.hypernode.io
example.com	TXT	600	v=spf1 include:spf.example.hypernode.io ~all

Validating your DNS records

To check if your DNS records have been configured correctly, please check our online DNS validator.

The first record is the mail auth record required by the TransIP mailplatform, used at Hypernode.
The second and third records are needed for automatic DKIM signing and DMARC
The fourth record is the SPF record. Please make sure you include spf.example.hypernode.io in your DNS’s SPF record.

Please check our DNS validator to confirm email can be sent successfully.

Additional audit options

If you’re sending email from your Hypernode with multiple domains you can perform an additional audit from the Command Line Interface. The following command can be used and performs a check based on the mail.logs from a week earlier.

app@yqc2sw-example-magweb-cmbl:~$ hypernode-mail-status domains --check
example.com - mail_auth: ok, dkim_hypernode: ok, spf_record: ok
example.nl - mail_auth: error, dkim_hypernode: ok, spf_record: ok

In this instance the audit gives a green light for example.com. From this domain you will be able to send email through your Hypernode and application. For the domain example.nl there is one mandatory DNS record missing, namely the x-transip-mail-auth This will lead to email from the domain example.nl to be not send and being held in your email queue. How to manage your email queue can be found in this article.
