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

Here is the DKIM-type TXT record to add (be careful, this record must not have a line break):

TXT Name

mta0._domainkey.example.com (example.com corresponding to your domain name).

TXT value

k=rsa;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDm8LOXQhq/UV16zgXP/qVqwtwNdiRLGVXWdQeLsOLSC6vAnib0wWFjXq2391OwtOmLjVut1l1U8WrQZQGNXiB3wANyN86tQOs9ER2WaMXBxpqqNRU/vd498PwjWXi47Zn+uWXf2tbH2Qd41OxROvplBgrHTm5dHfG60eflSpTIdQIDAQAB

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

Once you establish that Sarbacane is an authorized sender for your domain, you will need to add the service in your Enabled Senders.
