This document was written for On-Premises customers. If you’re a GreenArrow Cloud customer please contact our Technical Support Team. They will help you set up a new from address domain.
The 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 Sender field.
Overview
This document describes how to configure DKIM signing using the same domain as the RFC5322.From header (a.k.a., the “From Address Domain”) in authenticated messages. DKIM signing with the same domain as the RFC5322.From domain is strongly encouraged by mailbox providers and is highly recommended for email authentication methods such as DMARC
This document does not configure the domain name for use as the RFC5321.MailFrom domain; that is accomplished by methods described here and here.
Step 1: Identify the From Address Domain
This is the domain to be used in the RFC5322.From header, a.k.a., 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 [email protected].
Step 2: Identify the Person(s) Responsible for Managing DNS for the From Address Domain
Signing email messages with DKIM requires publishing a record (the DKIM public key) in DNS. Therefore, the person(s) responsible for managing DNS for the RFC5322.From domain will have to be involved in this process.
Step 3: Create a DKIM key
You will need to create a DKIM key for the RFC5322.From domain.
Note: Note the “Selector” that you use here. This is needed below in both the “Create a DNS Record” section and the “Yahoo Feedback Loop application” section.
Step 4: Create a DNS Record
After a new DKIM key is created, the next step is to create its DNS record. Detailed instructions, including screenshots, are in the Creating DNS Records for DKIM page.
Step 5: 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 DKIM is checked, and then reviewing the headers.
Another way is to visit the website AboutMy.Email, which offers a free, comprehensive method for reviewing not just your authentication setup but also many other aspects of your email configuration, all by simply sending an email message to a random address provided by the site.
Step 6: Setup the Yahoo Feedback Loop
Now that you have a working DKIM key, we recommend registering the domain with the Yahoo Feedback Loop.
