SPF(supported) / (dedicated subdomain)
DKIM(recommended)



This article covers the SPF and DKIM authentication processes for Bing Technologies and how they are managed in Valimail Enforce. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Configuring DKIM authentication for your Bing Technologies emails


To use DKIM with being Bing you can either add CNAME records to your DNS or insert a public/private key into your DNS.

To set up DKIM by adding CNAME records to your domain follow the below steps.


1. In your domain’s DNS records create 3 CNAME records as per our example below for example.com.au.


bingmail1._domainkey.example.com.au. 3600 IN CNAME dkim1.ci.com.au.

bingmail2._domainkey.example.com.au. 3600 IN CNAME dkim2.ci.com.au.

bingmail3._domainkey.example.com.au. 3600 IN CNAME dkim3.ci.com.au.


2. Once you added the records, please notify Bing customer service so they can verify them on their end.


Important:  If you manage DKIM in Valimail for your domain, you will need to add the 3 CNAME DKIM keys on your domain's Configuration page in Valimail Enforce.
