This document was written for On-Premises customers. If you’re a GreenArrow Cloud customer, then you can generally just start using your desired From address domain, as long as it’s not a domain like
hotmail.com that has a DMARC policy that forbids that type of use. For more advanced configurations, see the Adding A New Whitelabeled Cloud Domain doc.
Sender header is rarely used and is only needed if you cannot update DNS records for the domain in the From address. In GreenArrow Studio, this address is set in the
Step 1: Identify the From Address Domain
This is the domain to be used in the
From address of your email. The
From Address domain is the portion of the email address that comes after the
@ symbol. For example,
greenarrow-example.com is the
From Address domain in
Step 2: Create a DKIM key
You will need to create a DKIM key in your GreenArrow Engine’s web interface. Create the key for the
From Address domain above.
Note: Note the “Selector” that you use here. This is needed below in the “Yahoo Feedback Loop application” section.
Details on creating a new DKIM key are in the Creating a New DKIM Key page.
Step 3: Create a DNS Record
After a new DKIM key is created, the next step is to create its DNS record. Details instructions, including screenshots, are in the Creating DNS Records for DKIM page.
Step 4: Test Email Authentication
Once you have your email authentication set up, it is a good idea to test it out. You can do this by sending yourself a test email through GreenArrow to an email address that you own at an ISP where you know that Sender ID and DKIM are checked, and then reviewing the headers. For example, Hotmail / Outlook.com checks Sender ID and DKIM.
Step 5: Setup the Yahoo Feedback Loop
Now that you have a working DKIM key, we recommend registering it with the Yahoo Feedback Loop.
